x/(x+2)= 10/15

\frac{x}{x + 2} = \frac{10}{15}

x = 4

Solution steps

\frac{x}{x + 2} = \frac{10}{15}

Cross multiply

x \cdot 15 = 10 x + 20

Move

10 x

to the left side

5 x = 20

Divide both sides by

5

x = 4

Verify Solutions

Find undefined (singularity) points:

x = - 2

Combine undefined points with solutions:

x = 4

1 - \frac{2 x - 3}{x + 5} = \frac{x - 2}{10}

t, v = \frac{d}{t}

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

x - \frac{3}{x + 7} = \frac{5}{x + 7}

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