(x-4)/(3x+2)= 3/7

\frac{x - 4}{3 x + 2} = \frac{3}{7}

x = - 17

Solution steps

\frac{x - 4}{3 x + 2} = \frac{3}{7}

Cross multiply

7 x - 28 = 9 x + 6

Move

28

to the right side

7 x = 9 x + 34

Move

9 x

to the left side

- 2 x = 34

Divide both sides by

- 2

x = - 17

Verify Solutions

Find undefined (singularity) points:

x = - \frac{2}{3}

Combine undefined points with solutions:

x = - 17

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

\frac{15}{x - 1} = \frac{19}{x + 4}

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

\frac{x}{x + 9} - 5 = - \frac{5}{x + 9}

x^{2} + x - x^{- 1} = 0
