(-18-3)/(4v)=3

\frac{- 18 - 3}{4 v} = 3

v = - \frac{7}{4}

Decimal Notation

v = - 1.75

Solution steps

\frac{- 18 - 3}{4 v} = 3

Simplify

\frac{- 18 - 3}{4 v} : - \frac{21}{4 v}

- \frac{21}{4 v} = 3

Multiply both sides by

v

- \frac{21}{4} = 3 v

Switch sides

3 v = - \frac{21}{4}

Divide both sides by

3

v = - \frac{7}{4}

Verify Solutions

Find undefined (singularity) points:

v = 0

Combine undefined points with solutions:

v = - \frac{7}{4}

\frac{4}{x - 2} + 3 = \frac{19}{x - 2}

\frac{4}{x - 1} = \frac{3}{x - 2}

\frac{5.4}{2 y} = 9

\frac{4.22}{1} = \frac{809}{x}

2 x - \frac{128}{x ^{2}} = 0
