add your seven to both sides since it is subtracted.

gives= 3/4q=1

then divide by 3/4 on both sides because it is multiplied by q

gives= q=3/4

The process is correct in **Michele**'s post, but the math is faulty.

3/4 q - 7 = 8 3/4

Adding 7 to both sides gives you:

3/4 q = 15 3/4

You can either divide both sides by 3/4 or multiply by 4/3.

q = (15 3/4)(4/3) = (63/4) (4/3)

The 4s cancel each other out, leaving you with:

q = 63/3 = 21

I hope this helps a little more. Thanks for asking.
