(-4)/(5-2.5x)= 3/10

\frac{- 4}{5 - 2.5 x} = \frac{3}{10}

x = 7.33333 \dots

Solution steps

\frac{- 4}{5 - 2.5 x} = \frac{3}{10}

Cross multiply

- 40 = (5 - 2.5 x) \cdot 3

Switch sides

(5 - 2.5 x) \cdot 3 = - 40

Divide both sides by

3

5 - 2.5 x = - \frac{40}{3}

Move

5

to the right side

- 2.5 x = - \frac{55}{3}

Divide both sides by

- 2.5

x = 7.33333 \dots

Verify Solutions

Find undefined (singularity) points:

x = 2

Combine undefined points with solutions:

x = 7.33333 \dots

\frac{8}{x} - 2 = 2

0.26844 = \frac{20 - x}{x}

4500 = \frac{11400}{2 ( 1 + x )}

\frac{20 x}{x + 5} = 15

x + 3 = \frac{x + 5}{3 x + 9}
