-1/2x+3=-x+7
Plus x for both side
-1/2x+x+3=-x+7+x
1/2x+3=7
Subtract 3 from both side
1/2x+3-3=7-3
1/2x=4
Times 2 from both side
1/2x×2=4×2
x=8 is your final answer. Hope it help!

-1/2x + 3 = -x + 7

Add x to both sides, as well as subtracting 3 from both sides.

-1/2x + x = 7 - 3

Simplify.

1/2x = 4

Multiply both sides by 2.

x = 8
