Question

Rearrange the equation so q is the independent variable.

-7q+12r=3q-4r

Answer 1

r = (5/8)q

Explanation:

This means you want to express r in terms of q. Another way to say it is "solve for r."

Separate the variables by adding 4r+7q

16r = 10q

Divide by the coefficient of r

r = 10/16q

r = (5/8)q . . . . simplify
