(-20)/x =(-30)/(x-2)

\frac{- 20}{x} = \frac{- 30}{x - 2}

x = - 4

Solution steps

\frac{- 20}{x} = \frac{- 30}{x - 2}

Cross multiply

- 20 x + 40 = - x \cdot 30

Move

40

to the right side

- 20 x = - x \cdot 30 - 40

Move

x 30

to the left side

10 x = - 40

Divide both sides by

10

x = - 4

Verify Solutions

Find undefined (singularity) points:

x = 0, x = 2

Combine undefined points with solutions:

x = - 4

y, x = \frac{3 - y}{y + 1}

4 + \frac{6}{y} = \frac{5}{2}

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

\frac{2}{x + 4} = 0

- \frac{x}{( 0.1 x ^{2} + 4 ) ^{2}} = 0
