(3x-7)/(3x+9)= 5/6

\frac{3 x - 7}{3 x + 9} = \frac{5}{6}

x = 29

Solution steps

\frac{3 x - 7}{3 x + 9} = \frac{5}{6}

Cross multiply

18 x - 42 = 15 x + 45

Move

42

to the right side

18 x = 15 x + 87

Move

15 x

to the left side

3 x = 87

Divide both sides by

3

x = 29

Verify Solutions

Find undefined (singularity) points:

x = - 3

Combine undefined points with solutions:

x = 29

\frac{4 x - 3}{2 x + 1} = x - 1

20 = \frac{x ^{2}}{85 - x}

3.5 = \frac{0.25}{x}

\frac{10}{y} + \frac{5}{y} = 5

- \frac{6}{( x - 3 ) ^{2}} = 0
