(d+6)/(-9-d)<2

Solution

\frac{d + 6}{- 9 - d} < 2

Solution

d < - 9 or d > - 8

+1

Interval Notation

(- \infty, - 9) \cup (- 8, \infty)

Solution steps

\frac{d + 6}{- 9 - d} < 2

Rewrite in standard form

\frac{3 d + 24}{- 9 - d} < 0

Factor

\frac{3 d + 24}{- 9 - d} : \frac{3 ( d + 8 )}{- 9 - d}

\frac{3 ( d + 8 )}{- 9 - d} < 0

Divide both sides by

3

\frac{\frac{3 ( d + 8 )}{- 9 - d}}{3} < \frac{0}{3}

Simplify

\frac{d + 8}{- 9 - d} < 0

Identify the intervals

d < - 9 or d > - 8
