Answer:
x=-1
See below for instructions.
Explanation:
Basically you want to figure out what x is in order for the equation to equal 7. We want the left side of the equation to equal the right side, so we need to make the 7 on the left side equal to -7 so the 14 will make it positive 7, therefore making it equal: 7=7
So what can we multiply 7 by so that it equals -7?
If you answered -1, youd be correct.
7(-1) + 14 = 7
-7 + 14 = 7
7=7
Therefore for the equation to be true, x needs to equal -1.
x=-1
