32-q+0.25q=15.50
32 - 1.25q = 15.50
-1.25q = -16.5
q = 13.2
32-q+0.25q=15.50
Can someone explain how to solve this?

Subtract your 32 from 15.5, then add the q numbers together. divide. Plug back in to check.
unknown on one side, numbers on the other
-q + 0.25q = 15.50 - 32
consolidate ... -0.75q = -16.50
divide by -0.75
-q + 0.25q = 15.50 - 32
consolidate ... -0.75q = -16.50
divide by -0.75
Yeah But I dont under stand how q + -.25q is equalled to -0.75q
it's ... -q + 0.25q
I think Scott is right. -1 + 0.25 = -0.75
Right I forgot that it still means one.
