Question

Solve the formula below for the specified variable. P=2L+2W P = 2 L + 2 W , for W

Answer 1

Answer:

Step-by-step explanation:

The given equation is

P=2L+2W

We want to make the specified variable, W the subject of the formula. The first step would be to subtract 2W from the left hand side and the right hand side of the equation. It becomes

P - 2W = 2L + 2W - 2W

P - 2W = 2L

The next step would be to subtract P from the left hand side and the right hand side of the equation. It becomes

P - P - 2W = 2L - P

- 2W = 2L - P

The next step would be to divide the left hand side and the right hand side of the equation by - 2. It becomes

- 2W/-2 = (2L - P)/-2

W = - L + P/2

W = P/2 - L
