Please help me explain how to answer this algebra problem to my child. If a b=-.8 and a*b=-.4, what do a and b equal?
Heidi
So first you would divide each side of the equation by -0.8, because that's what b is, so you can isolate the remaining unknown variable, a. Then you'd have a=0.5, and b=-0.8.
