(280)/(x+2)=20+2.5x

\frac{280}{x + 2} = 20 + 2.5 x

x = 6, x = - 16

Solution steps

\frac{280}{x + 2} = 20 + 2.5 x

Multiply both sides by

10

\frac{2800}{x + 2} = 200 + 25 x

Multiply both sides by

x + 2

2800 = 200 (x + 2) + 25 x (x + 2)

Solve

2800 = 200 (x + 2) + 25 x (x + 2) : x = 6, x = - 16

x = 6, x = - 16

Verify Solutions

Find undefined (singularity) points:

x = - 2

Combine undefined points with solutions:

x = 6, x = - 16

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

2 - \frac{5}{x} = \frac{10}{x} - 1

\frac{∣ x + 1 ∣}{x - 2} = 0

\frac{1}{x} = \frac{4}{x - 9}

\frac{2}{5 x - 1} = - \frac{3}{4}
