can someone please tell me how to solve problems like this>>>> 3/4q -7=8 3/4 is a fraction
Thanks for helping me
add your seven to both sides since it is subtracted.
then divide by 3/4 on both sides because it is multiplied by q
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.
