Help!!!! the integer that makes the following addition sentence true.
? + (-11) + 12 + =-16
Answer:
-17
Step-by-step explanation:
I will represent the question mark with the variable [tex]x[/tex].
[tex]x - 11 + 12 = -16[/tex]
To solve for [tex]x[/tex], we need to isolate it.
To do this, subtract 12 from both sides.
[tex]x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28[/tex]
Then, add 11 to both sides.
[tex]x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17[/tex]
[tex]x = -17[/tex]
So, the integer that makes the equation true is -17.
Seven subtracted from x is greater than 15.
