(12)/x+(18)/(x+4)=9

\frac{12}{x} + \frac{18}{x + 4} = 9

x = 2, x = - \frac{8}{3}

Decimal Notation

x = 2, x = - 2.66666 \dots

Solution steps

\frac{12}{x} + \frac{18}{x + 4} = 9

Multiply by LCM

12 (x + 4) + 18 x = 9 x (x + 4)

Solve

12 (x + 4) + 18 x = 9 x (x + 4) : x = 2, x = - \frac{8}{3}

x = 2, x = - \frac{8}{3}

Verify Solutions

Find undefined (singularity) points:

x = 0, x = - 4

Combine undefined points with solutions:

x = 2, x = - \frac{8}{3}

0.6 = \frac{x - 0.05 x - 34}{x}

\frac{x - 7}{x - 9} = \frac{3}{4}

\frac{1}{2 x + 5} = \frac{3}{x - 5}

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

\frac{7}{15} = \frac{12}{5 x}
