Question

5-3(w+4)=w-7 please show work.

Answer 1

5-3w-12 = w-7
5-12+7 = 4w
4w = 14
w = 14/4
w = 7/2

Answer 2

the answer is supposed to be 0.

Answer 3

5-3w-12=w-7 distribute the -3 to (w+4)
-7-3w=w-7 combine like terms (5-12), then add 7 to both sides
and add 3w to both sides
0=4w divide by 4 both sides
0=w
