x-9/(x+4)=(4x)/(x+4)

x - \frac{9}{x + 4} = \frac{4 x}{x + 4}

x = 3, x = - 3

Solution steps

x - \frac{9}{x + 4} = \frac{4 x}{x + 4}

Multiply both sides by

x + 4

x (x + 4) - 9 = 4 x

Solve

x (x + 4) - 9 = 4 x : x = 3, x = - 3

x = 3, x = - 3

Verify Solutions

Find undefined (singularity) points:

x = - 4

Combine undefined points with solutions:

x = 3, x = - 3

\frac{12}{x + 2} = \frac{9}{x + 5}

15 - \frac{12}{x} = - 33

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

x, \frac{y - 2 z}{x - z} = 0

\frac{9}{2 x} + \frac{1}{2} = 2
