-3=-2/(u+2)

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

u = - \frac{4}{3}

Decimal Notation

u = - 1.33333 \dots

Solution steps

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

Multiply both sides by

u + 2

- 3 (u + 2) = - 2

Divide both sides by

- 3

u + 2 = \frac{2}{3}

Move

2

to the right side

u = - \frac{4}{3}

Verify Solutions

Find undefined (singularity) points:

u = - 2

Combine undefined points with solutions:

u = - \frac{4}{3}

(x + \frac{1}{x})^{5} = 3^{5}

8 = - \frac{4}{v}

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

\frac{1}{4.75} = \frac{6}{x}

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