Oh honey, solving for w in 2l + 2w = P is as easy as stealing candy from a baby. Just subtract 2l from both sides and then divide by 2. Voila, w = (P - 2l) / 2. Now go show off your math skills like the boss you are.

2l + 2w = P
Subtract 2l from both sides: 2w = P - 2l
Divide both sides by 2: w = P/2 - l
P = 100 l = 30 w = 20
5w+2 = 2w+5 5w-2w = 5-2 3w = 3 w = 1
p=2l+2w
'W' and 'L' are independent variables. 'P' is the dependent variable. '2' and '2' are the constants.
To solve for area: A=lw (Area equals length times width) The length and width are both 12. Substitute 12 for l and w. A=12x12 Multiply. A=144 The room has an area of 144 units. To solve for perimeter: P=2l+2w (Perimeter equals two time the length plus two times the width). Substitute 12 for l and w. P=(2x12)+(2x12) Simplify. P=24+24 P=48 The room has a perimeter of 48 units.
