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

\frac{3}{x + 4} - 7 = - \frac{4}{x + 4}

x = - 3

Solution steps

\frac{3}{x + 4} - 7 = - \frac{4}{x + 4}

Multiply both sides by

x + 4

3 - 7 (x + 4) = - 4

Move

3

to the right side

- 7 (x + 4) = - 7

Divide both sides by

- 7

x + 4 = 1

Move

4

to the right side

x = - 3
