7/(x+4)= 9/(5x-6)

\frac{7}{x + 4} = \frac{9}{5 x - 6}

x = 3

Solution steps

\frac{7}{x + 4} = \frac{9}{5 x - 6}

Cross multiply

35 x - 42 = 9 x + 36

Move

42

to the right side

35 x = 9 x + 78

Move

9 x

to the left side

26 x = 78

Divide both sides by

26

x = 3

Verify Solutions

Find undefined (singularity) points:

x = - 4, x = \frac{6}{5}

Combine undefined points with solutions:

x = 3

\frac{3}{x - 6} = \frac{7}{x + 2}

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

0.2 = \frac{x ^{2}}{35 - x}

\frac{4 r}{5 r + 6} = \frac{1}{6}

x^{- 2} = \frac{1}{4}
