2-5/(x+4)=x

2 - \frac{5}{x + 4} = x

x = 1, x = - 3

Solution steps

2 - \frac{5}{x + 4} = x

Multiply both sides by

x + 4

2 (x + 4) - 5 = x (x + 4)

Solve

2 (x + 4) - 5 = x (x + 4) : x = 1, x = - 3

x = 1, x = - 3

Verify Solutions

Find undefined (singularity) points:

x = - 4

Combine undefined points with solutions:

x = 1, x = - 3

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

\frac{10}{x} = 7 - x

x - \frac{x + 7}{x - 10} = \frac{5}{x - 10}

\frac{3}{2} = \frac{3}{2 x} - \frac{6}{5 x}

\frac{3}{x ^{2}} - \frac{7}{x} + 2 = 0
