Numerous engineering and scientific applications require finding solutions to a set of equations. Ex: 8x + 7y = 38 and 3x - 5y = -1 have a solution x = 3, y = 2. Given integer coefficients of two linear equations with variables x and y, use brute force to find an integer solution for x and y in the range -10 to 10.
Ex: If the input is:
8
7
38
3
-5
-1
Then the output is:
x = 3 , y = 2
Use this brute force approach:
For every value of x from -10 to 10
For every value of y from -10 to 10
Check if the current x and y satisfy both equations. If so, output the solution, and finish.
Ex: If no solution is found, output:
There is no solution
Assume the two input equations have no more than one solution.
Note: Elegant mathematical techniques exist to solve such linear equations. However, for other kinds of equations or situations, brute force can be handy.
The brute strength method determines if each x and y value satisfies both conditions. To do this, we must iterate through each result in the specified range and insert them into both models.
What are Elegant mathematical technique?ALGORITHM :
1. Take the values of all coefficients and SET flag = FALSE
2. Run a FOR loop for x in range (-10, 11). 11 won't be included.
2a. Inside the first FOR, start the y FOR loop in range(-10,11). 11 won't be included
2b. Inside the y FOR loop, check IF for a particular value of x and y both the equations satisfied.
2c. If yes, set flag TRUE and print values of x and y.
2d. ELSE the flag stays FALSE.
END FOR Y
END FOR X
3. Check if flag = FALSE, then print NO SOLUTION
PYTHON CODE :
a=int(input()) #taking input for each coefficient
b=int(input())
c= int(input())
a1= int(input())
b1= int(input())
c1= int(input())
flag = False
for x in range(-10,11): #checking for all values of x in range -10 to 10
for y in range(-10,11): #checking for all values of x in range -10 to 10
if (a x + b y – c == 0) and (a1*x + b1*y - c1 == 0) : #checking if the x and y values satisfy the equation
flag = True #setting the flag if solution is found
print('Solution : x = {-10, 10}, y = {-10, 10}'.format(x,y)) #if they satisfy print x & y
if flag = False : #if flag stays false, that means there is no solution
print('No solution')

Briefly explain the importance of doing backup in systems administration and explain in detail any three methods for performing backup!?
Answer:
Importance of backup in system administration:
Backups are crucial in system administrations for preserving continuity and protecting against specific types of hardware failures, service interruptions, and human mistakes. To aid a company in recovering from an unexpected catastrophe, backup copies make it possible to restore data to a previous point in time. To safeguard against primary data loss or corruption, it is essential to save a copies of data on a different media. When a system administrator create a backup, he makes a copy of the data that you can restore if your main data is lost. These errors may be the consequence of faulty hardware or software, corrupted data, or a human error like a targeted attack or an unintentional deletion. System backup and recovery is therefore a crucial skill for system administrators as well as the companies they work for.
Three methods for performing backup:
Disk image: A efficient method to back up not only the files and directories but also everything else on the system is by creating a disk image. If a user have a disk image, the user can restore everything, including the operating system, applications, data, and more, so the user won't have to worry about any difficulties. Placing the disk image-containing DVD into the DVD-ROM to restore the backup. Additionally, just attach an external HDD to the computer if the user have a disk image that they made.External hard drive: The most common backup method is to use an external hard drive or even a USB flash drive. An HDD can be easily, quickly, and affordably backed up. It is effective since consumers may carry their portable backup with them wherever they go. Cloud backup: Cloud backup or Online backup has been around for a while, but not many people really utilize it. But the greatest backup technique by far is cloud backup. The user does not have to worry about hardware problems because their files are saved in the cloud and can be accessed from anywhere because the backups are automatically produced and everything is synchronized. It is one of the greatest methods to backup, especially when you consider that the contents are encrypted and stored securely.

A square QR code contains 40×40 tiny squares (pixels) where each tiny square represents a 0 or a 1. Calculate how many bytes of data can be stored on the QR code
Answer:
Explanation:
QR Codes are made of multiple rows and columns. The combination of these rows and columns makes a grid of modules (squares). There can be a maximum of 177 rows and 177 columns which means the maximum possible number of modules is 31,329. With the eye, these are just small squares and mean very little, but the exact arrangement of those modules allows the QR Code to encode its data. This means that, unlike traditional barcodes which are 1 dimensional and use 1 row of lines, QR Codes use 2 dimensions which allows them to store a lot more data in the same area of space.
