x/(x-1)= 3/(x+7)

\frac{x}{x - 1} = \frac{3}{x + 7}

x = - 1, x = - 3

Solution steps

\frac{x}{x - 1} = \frac{3}{x + 7}

Cross multiply

x (x + 7) = (x - 1) \cdot 3

Solve

x (x + 7) = (x - 1) \cdot 3 : x = - 1, x = - 3

x = - 1, x = - 3

Verify Solutions

Find undefined (singularity) points:

x = 1, x = - 7

Combine undefined points with solutions:

x = - 1, x = - 3

\frac{1}{4 ( 2 ( x - 1 ) + 10 )} = x

2 = \frac{x + 3}{x - 11}

\frac{180 ( n - 2 )}{n} = 160

d, \frac{20}{d} = - 15

\frac{180 ( n - 2 )}{n} = 120
