\frac{1}{2} = \frac{3 - 15}{- 2 - a}

a = 22

Solution steps

\frac{1}{2} = \frac{3 - 15}{- 2 - a}

Cross multiply

- 2 - a = - 24

Move

2

to the right side

- a = - 22

Divide both sides by

- 1

a = 22

Verify Solutions

Find undefined (singularity) points:

a = - 2

Combine undefined points with solutions:

a = 22

r, F = G \frac{mn}{r ^{2}}

\frac{4}{x} = \frac{14}{5 x} + 12

- \frac{3}{x + 1} = \frac{x - 10}{2 x}

\frac{x ^{2}}{( 12.2 - 2 x ) ^{2}} = 5

3 + \frac{2 x}{x - 4} = \frac{8}{x - 4}
