9-x/(x+3)=-5/(x+3)

9 - \frac{x}{x + 3} = - \frac{5}{x + 3}

x = - 4

Solution steps

9 - \frac{x}{x + 3} = - \frac{5}{x + 3}

Multiply both sides by

x + 3

9 (x + 3) - x = - 5

Expand

9 (x + 3) - x : 8 x + 27

8 x + 27 = - 5

Move

27

to the right side

8 x = - 32

Divide both sides by

8

x = - 4

Verify Solutions

Find undefined (singularity) points:

x = - 3

Combine undefined points with solutions:

x = - 4

\frac{1}{4} + \frac{1}{6} = \frac{1}{x}

\frac{4}{5 x + 2} - \frac{12}{15 x + 6} = 0

x - \frac{3 x}{x - 8} = 3

\frac{4}{x} + 1 = \frac{2 x + 2}{x}

\frac{x}{x - 6} + \frac{x + 2}{x - 6} = 6
