Question

Solve the equation for the indicated variable. A(b +c) = bc, for b

Answer 1

So A(b+c) =bc

Distrubite the A to get Ab+Ac=bc

Subtract Ab on both sides of the equation to get Ac= bc-Ab

Factor b to get Ac= b(c-A)

Divide by (c-a) on both sides to get

b =
`(Ac)/(c-A)` (or if you can't see it, b = ((Ac)/(c-A))
