3=2+2/(z+2)

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

z = 0

Solution steps

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

Move

2

to the left side

1 = \frac{2}{z + 2}

Multiply both sides by

z + 2

z + 2 = 2

Subtract

2

from both sides

z + 2 - 2 = 2 - 2

Simplify

z = 0

Verify Solutions

Find undefined (singularity) points:

z = - 2

Combine undefined points with solutions:

z = 0

\frac{4}{x} = \frac{13}{4 x} + 3

\frac{5}{x - 4} = \frac{3}{x + 8}

- \frac{2}{x} = \frac{7}{x - 9} - 1

V, d = \frac{m}{V}

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