Answer 2

x = -3

Explanation:

First you need to distribute the 7 to (x + 4):

7x + 28 = 8x + 31

Then subtract 7x from both sides, making it cancel out on the left since 7x - 7x cancel each other out.

7x + 28 = 8x + 31

-7x -7x

_____________

28 = x + 31

Then subtract 31 from both sides, making it cancel out on the right side:

28 = x + 31

-31 - 31

_________

-3 = x
