Hi, I am just trying to relearn all the math I have forgot and now that im going back to school
Keep getting wrong answer on this one



Can anyone help me out?
answer is -15/8

why dont you show your arithmetic step by step so we can show you were you went wrong?

/edit: is that a on the far left part of the problem? or just labeling it?

I'll try and type it out but typing fractions is a pain give me a min.

(-4b - 2)/(4a) - (3a - 1)/(5b - 3) = (-20 - 2)/(16) - (12 - 1)/(25 - 3) = -22/16 - 11/22 = -11/8 - 4/8 = -15/8

just use _______ for simplicity then

eg: instead of 1/2, you can do:

1
______
2

This post made me realize how blind I am
I thought it was Multiplying fractions the whole time T_T
