Question

Solve for L.
P = 2L + 2W

Answer 1

subtract 2W from both sides

2L = P - 2W

divide both sides by 2

L = P/2 - W

Answer 2

The answer is
`L=(P-2*W)/(2)`

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\\(P-2*W)/(2)=(2*L)/(2)\\ L=(P-2*W)/(2)`

Finally, the expression for L is
`L=(P-2*W)/(2)`
