3/(x+5)= 1/(x+2)

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

x = - \frac{1}{2}

Decimal Notation

x = - 0.5

Solution steps

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

Cross multiply

3 x + 6 = x + 5

Move

6

to the right side

3 x = x - 1

Move

x

to the left side

2 x = - 1

Divide both sides by

2

x = - \frac{1}{2}

Verify Solutions

Find undefined (singularity) points:

x = - 5, x = - 2

Combine undefined points with solutions:

x = - \frac{1}{2}

8 x - \frac{1}{x ^{2}} = 0

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

\frac{3}{x - 6} = \frac{5}{x}

\frac{- 9}{4 x} = \frac{3}{4 x - 16}

5 (1 + 2 m) = \frac{1}{2 ( 8 + 20 m )}
