(2x-10)/(3x-20)= 7/8

\frac{2 x - 10}{3 x - 20} = \frac{7}{8}

x = 12

Solution steps

\frac{2 x - 10}{3 x - 20} = \frac{7}{8}

Cross multiply

16 x - 80 = 21 x - 140

Move

80

to the right side

16 x = 21 x - 60

Move

21 x

to the left side

- 5 x = - 60

Divide both sides by

- 5

x = 12

Verify Solutions

Find undefined (singularity) points:

x = \frac{20}{3}

Combine undefined points with solutions:

x = 12

\frac{8 x}{x + 1} + 1 = \frac{8}{x ^{2} + x}

\frac{( x ^{2} + x )}{x} = 4

\frac{1}{x + 6} = 2

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

\frac{x ^{2}}{x + 6} + \frac{x}{x ^{2} - 6} = 2
