Question

Rearrange the equation so q is the independent variable.

−7q+12r=3q−4r

Answer 1

q=8/5 r

Explanation:

Step 1: add -3q to both sides

-7q+12r+-3q=3q-4r+-33

-10q+12r=4r

Step 2: Add -12r to both sides

-10q+12r+-12r=-4r+-12r

-10q=-16r

Step 3: Divide both sides by -10.

-10q/-10=-16r/-10

q=8/5r
