3/4q-7=8

*please also post a website

• Pre-Algebra -

3/4q-7=8

First get the known quantities on one side. Add 7 to both sides.

3/4q -7 + 7 = 8 + 7

3/4q = 15

Divide both sides by 3/4

q = 15 / (3/4)

q = 15 * (4/3)

q = 60/3 = 20

~~~~~~~~~~~~~~~~~~~~~~~~~~

Proof:

[(3/4) * 20] -7 = 8
15 - 7 = 8
