Solve for L:<br> P=2L+2W

Korvikt [17]

Answer:

$L=\frac{1}{2}P-W$

Step-by-step 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 $2$ .

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

$L=\frac{1}{2}P-W$

Answer:

$L=\frac{1}{2}P-W$
