Question

Prompt

The given equation

\frac{2}{c} - \frac{7}{d} = 5

relates the variables

c

and

d

, where

c

and

d

are greater than 1. Which equation correctly expresses

d

in terms of

c

d = \frac{c}{7 ( 2 - 5 c )}

d = \frac{7 c}{2 - 5 c}

d = \frac{7 ( 2 - 5 c )}{c}

d = \frac{2 - 5 c}{7 c}
