The value of the equation is x² - x - 1 = 0
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
x - ( 1/x ) = 1 be equation (1)
On simplifying the equation , we get
( x² - 1 ) / x = 1
Multiply by x on both sides of the equation , we get
x² - 1 = x
Subtracting x on both sides of the equation , we get
x² - x - 1 = 0
Now , given that ( x / ( x² + 3x - 1 ) ) = 1/4
On simplifying the equation , we get
Cross multiplying the equation , we get
4x = ( x² + 3x - 1 )
Subtracting 4x on both sides of the equation , we get
x² - x - 1 = 0
Hence , the equation is x² - x - 1 = 0

What is an example of a function that is its own inverse?.
One example of a function that is its own inverse is the square root function. The square root function takes a number and returns its inverse, which is always negative.
For example, the square root of 4 is equal to -2, and the square root of -3 is equal to 3. This means that you can multiply a number by -1 and then take the square root to get the same number as the original number. This proves that the inverse of a number is always a negative number. The opposite of a square is known as a rectangle. This shows that the square functions as its inverse. Another example of a function that is its own inverse is the exponential function. The exponential function takes two numbers and returns the reciprocal of their product. This means that the exponential function is also its own inverse because the reciprocal of a product is equal to the product of the reciprocals.

A man deposits 400 naira with a bank which pays 5% interest per annum. How many years will the money in his savings account grow up to 500 naira?
Answer: The formula for compound interest is A = P(1 + r/n)^(nt) where A is the amount, P is the principal (initial deposit), r is the interest rate, t is the time in years, and n is the number of times compounded per year.
To find out how many years it will take for the money to grow to 500 naira, we can set A equal to 500, P equal to 400, r equal to 5% (or 0.05), and n equal to 1 (since the interest is compounded annually).
Plugging these values into the formula, we get:
500 = 400(1 + 0.05)^t
By solving this equation, t = 3.32 years.
So, it will take 3.32 years for the money in the savings account to grow to 500 naira.

How do you do algebraic expressions Grade 6?.
One can solve basic algebraic expressions by following these steps.
In grade 6, students typically learn to solve basic algebraic expressions by following these steps:
Identify the variable and the coefficient (number in front of the variable) in the expression.
Use the order of operations (PEMDAS) to simplify any arithmetic within the expression.
Use the distributive property to combine like terms.
Isolate the variable on one side of the equation by using inverse operations (such as adding or subtracting the same value from both sides, or dividing or multiplying both sides by the same non-zero value).
Substitute in a value for the variable to find the numerical value of the expression.
It's good to practice with a lot of examples and check the solutions and ask for help if needed.
Example:
Solve for x: 3x + 2 = 12
variable is x, coefficient is 3
nothing to simplify
nothing to combine
subtract 2 from both sides: 3x = 10
divide both sides by 3: x = 10/3 or 3.3333
x = 3.3333
It's important to note that solving algebraic expressions can become more complex as the student progresses, but the basic steps remain the same.

The linear equation that gives the rule for this table is y = 19x - 12.
What is a linear equation?A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The standard linear equation can be represented as:
y = mx + b
where, m is the slope and b is the y-intercept of the line.
From the table we can see the two points through which the point passes is:
(x1, y1) = (2, 26)
(x2, y2) = (3, 45)
The slope of the line is given by:
m = (y2 - y1) / (x2 - x1)
m = (45 - 26) / (3 - 2)
m = 19 / 1 = 19
The slope m = 19.
The point-slope form of the line can be written as:
y - y1 = m (x - x1)
y - 26 = 19 (x - 2)
y - 26 = 19x - 38
y = 19x - 38 + 26
