a) = 4 + 4.SolveforL.
b) = + 3 + 4.Solveforb.
Part a) Solve for L
we have
P=4L+4V
solve for L ----> that means, isolate the variable L
so
subtract 4V both sides
P-4V=4L
Divide by 4 both sides
(P--4V)/4=L
REwrite
L=(P/4)-V
Part b
we have
= + 3 + 4
solve for b ------> isolate the variable b
subtract (3a+4c) both sides
P-(3a+4c)=b
REwrite
b=P-3a-4c
