Answer:
a = (D+f) * g
Step-by-step explanation:
We want to isolate a
a/g -f =D
Add f to each side
a/g -f+f = D+f
a/g = D+f
Multiply each side by g
a/g *g = (D+f) * g
[tex]\dfrac{a}{g}-f=D\qquad\text{add f to both sides}\\\\\dfrac{a}{g}=D+f\qquad\text{multiply both sides by }\ g\neq0\\\\\boxed{a=g(D+f)}\qquad\text{use distributive property}\\\\\boxed{a=Dg+fg}[/tex]
