Question

Help!!!! the integer that makes the following addition sentence true.

​
? + (-11) + 12 + =-16

Answer 1

-17

As you can see the end result will end up with -16

Answer 2

-17

Explanation:

I will represent the question mark with the variable
`x`.

`x - 11 + 12 = -16`

To solve for
`x`, we need to isolate it.

To do this, subtract 12 from both sides.

`x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28`

Then, add 11 to both sides.

`x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17`

`x = -17`

So, the integer that makes the equation true is -17.
