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

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

x = \frac{5}{2}

Decimal Notation

x = 2.5

Solution steps

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

Cross multiply

x + 2 = 3 x - 3

Move

2

to the right side

x = 3 x - 5

Move

3 x

to the left side

- 2 x = - 5

Divide both sides by

- 2

x = \frac{5}{2}

Verify Solutions

Find undefined (singularity) points:

x = 1, x = - 2

Combine undefined points with solutions:

x = \frac{5}{2}

\frac{0.7}{1.4} = \frac{15}{x}

6 z - \frac{4}{1 + 2 z} = 3

10 = 500 (b)^{- 3}

\frac{x}{x - 4} = \frac{4}{x - 4} + 5

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