Question

-7q+12r=3q-4r Write a formula for g(q) in terms of q.

Answer 1

Formula in terms of q is: $q=\frac{8r}{5}$

Step-by-step explanation:

We need to write the formula in terms of q of the equation: $-7q+12r=3q-4r$

We will solve the given equation to find the formula in terms of q

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

Adding -3q on both sides

$-7q+12r-3q=3q-4r-3q\\-10q+12r=-4r$

Adding -12r on both sides

$-10q+12r-12r=-4r-12r\\-10q=-16r$

Divide both sides by -10

$\frac{-10q}{-10}=\frac{-16r}{-10}\\q=\frac{8r}{5}$

So, formula in terms of q is: $q=\frac{8r}{5}$
