3x474x4Solution3x474x4 To isolate x Add 4x4 on both sides 3x

3/(x+4)-7=-4/(x+4)

To isolate x Add 4/(x+4) on both sides:

3/(x+4) -7 + 4/(x +4) = -4/(x +4) +4/(x+4)

7/( x+4) -7 =0

Add 7 on both sides:

7/(x 4) -7 +7 = 7

7/(x +4) =7

Divide both sides by 7 we get:

1/(x+4) = 1

multiply both sides by (x+4) we get:

1 = x+4
