Answer:
x = -8
Step-by-step explanation:
1st step: switch sides, 3 - x/2 =7
2nd step: subtract 3 from both sides, 1-x/2-3 = 7-3
3rd step: simplify, -x/2 = 4
4th step: multiply both sides by 2, 2(-x/2) = 4*2
5th step: simplify, -x = 8
6th step: divide both sides by -1, -x/-1 = 8/-1
7th step: simplify, x= -8
