Question

For a given input value q, the function g outputs a value r to satisfy the following equation.

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

Write a formula for g(q) in terms of q

Answer 1

Explanation:

Let's solve for q. Add -3q to both sides

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

-10q+12r=-4r

Add -12r to both sides.

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

-10q=-16r

Divide both sides by -10.

-10q & -16r both minus 10.

Your answer should be q=8/5r
