Question

Solve for L. P = 2L + 2W

Answer 1

Answer:

The answer is $L=\frac{P-2*W}{2}$

Step-by-step explanation:

In order to solve for L, we have to free the L variable.

Mathematically, we have to subtract, add, multiply or divide the same terms from each side of the equation. In that way, we can change the equation and free a variable.

Therefore, we have to subtract 2*W term, and then we have to divide by 2.

So,

$P=2*L+2*W\\P-2*W=2*L+2*W-2*W\\P-2*W=2*L\\\frac{P-2*W}{2}=\frac{2*L}{2}\\ L=\frac{P-2*W}{2}$

Finally, the expression for L is $L=\frac{P-2*W}{2}$

Answer 2

Subtract 2W from both sides

2L = P - 2W

divide both sides by 2

L = P/2 - W
