3/a =7

Solution

\frac{3}{a} = 7

a = \frac{3}{7}

Solution steps

\frac{3}{a} = 7

Multiply both sides by

a

3 = 7 a

Switch sides

7 a = 3

Divide both sides by

7

a = \frac{3}{7}

Verify Solutions

Find undefined (singularity) points:

a = 0

Combine undefined points with solutions:

a = \frac{3}{7}

\frac{5}{6} = \frac{x - 1}{2 x - 1}

\frac{1}{2 x - 5} = 4

\frac{3}{a} + \frac{4}{14 - a} = 1

\frac{0.3}{x} = \frac{x}{27}

1 - \frac{y}{y - 5} = - 3
