Question

Given the equation P = 2w + 2l solve for w.

Answer 1

P = 2w + 2l....subtract 2l from both sides
P - 2l = 2w....divide both sides by 2
(P - 2l)/2 = w

Answer 2

Answer:

The correct option is D.

Step-by-step explanation:

The given equation is

$P=2w+2I$

We need to solve the above equation for w.

Subtract 2I from both sides.

$P-2I=2w+2I-2I$

$P-2I=2w$

Divide both sides by 2.

$\frac{P-2I}{2}=\frac{2w}{2}$

$\frac{P-2I}{2}=w$

The formula for w is $w=\frac{P-2I}{2}$.

Therefore the correct option is D.
