\frac{20}{- d} = - 15

d = \frac{4}{3}

Decimal Notation

d = 1.33333 \dots

Solution steps

\frac{20}{- d} = - 15

Simplify

\frac{20}{- d} : - \frac{20}{d}

- \frac{20}{d} = - 15

Multiply both sides by

d

- 20 = - 15 d

Switch sides

- 15 d = - 20

Divide both sides by

- 15

d = \frac{4}{3}

Verify Solutions

Find undefined (singularity) points:

d = 0

Combine undefined points with solutions:

d = \frac{4}{3}

x, \frac{3}{x} + 7 y + z = 9

\frac{5}{x + 2} - \frac{2 x - 1}{5} = 0

\frac{8 x}{x + 1} = 4 - \frac{8}{x + 1}

\frac{4 x}{x - 1} + \frac{x}{x - 2} = 0

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