Question

Solve for L:
P=2L+2W

Answer 1

`L=(1)/(2)P-W`

Explanation:

Let's solve for L.

`P=2L+2W`

Step 1: Flip the equation.

`2L+2W=P`

Step 2: Add
`-2W` to both sides.

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

`2L=P-2W`

Step 3: Divide both sides by
`2`.

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

`L=(1)/(2)P-W`

Answer:

`L=(1)/(2)P-W`
