Question

Rearrange the equation algebraically to solve for the unknown quantity.

3. Solve the equation p = 21 + 2w for l.

1. 2L = P-2W

2. L = P/2-2W

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

4. L = (P + 2W)/2

PLEASE HELP ME !!

Answer 1

Given:

Consider the given equation is

`P=2L+2W`

To find:

The solution of the equation for l.

Solution:

We have,

`P=2L+2W`

Substract 2W from both sides.

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

`P-2W=2L`

Divide both sides by 2.

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

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

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

Therefore, the correct option is 3.
