(12)/(x+5)= 4/(x-3)

\frac{12}{x + 5} = \frac{4}{x - 3}

x = 7

Solution steps

\frac{12}{x + 5} = \frac{4}{x - 3}

Cross multiply

12 x - 36 = 4 x + 20

Move

36

to the right side

12 x = 4 x + 56

Move

4 x

to the left side

8 x = 56

Divide both sides by

8

x = 7

Verify Solutions

Find undefined (singularity) points:

x = - 5, x = 3

Combine undefined points with solutions:

x = 7

x, y = \frac{x}{x + y}

x, \frac{y - x}{y + x} = 0

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

\frac{4}{k} + 3 = 14

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