Question

Please help, I have an algebra test tomorrow and i'm trying to understand problems like this.

Solve for L
P = 2(l+w)

Answer 1

L=P/2-W

Explanation:

P=2(L+w) - Solve for L

1) Use the distributive property on the right side of the equation:

P=2L+2w

2) Subtract both sides by 2w:

P-2w=2L

3) Divide both sides by 2 to Isolate L:

P/2-W=L
