Question

P=2a+3b+4c solve for c

Answer 1

C=P/4-a/2-3b/4

Explanation:

Question: P=2a+3b+4c

1) Subtract 2a and 3b from both sides:

P-2a-3b=4C

2) Divide everything by 4:

C=P/4-2a/4-3b/4

3) Simplify 2a/4: (a/2)

C=P/4-a/2-3b/4

Answer 2

(P-2a-3b)/4=c

Explanation:

First, isolate the variable we are solving for, c (P-2a-3b=4c). Now, divide by 4 to get c completely alone ((P-2a-3b)/4=c).
