x-5/(x+7)=(3x)/(x+7)

x - \frac{5}{x + 7} = \frac{3 x}{x + 7}

x = 1, x = - 5

Solution steps

x - \frac{5}{x + 7} = \frac{3 x}{x + 7}

Multiply both sides by

x + 7

x (x + 7) - 5 = 3 x

Solve

x (x + 7) - 5 = 3 x : x = 1, x = - 5

x = 1, x = - 5

Verify Solutions

Find undefined (singularity) points:

x = - 7

Combine undefined points with solutions:

x = 1, x = - 5

\frac{2}{x ^{2}} + \frac{3}{x} - 2 = 0

\frac{- 1}{x + 1} = \frac{5}{x + 2}

0 = 2 x - \frac{2}{x ^{2}}

7 + \frac{1}{x + 5} = \frac{5 x}{x + 5}

\frac{4 x}{x + 3} - \frac{1}{x} = \frac{1}{x}
