Solve for w: P=2L+2W
P=2L+2W
2W = P - 2L
W = (P - 2L) / 2
To solve for w in the equation P = 2L + 2W, we need to isolate the variable w by performing a few algebraic steps.
Step 1: Distribute the 2 to both L and W.
P = 2L + 2W
Step 2: Rearrange the equation to isolate W on one side by subtracting 2L from both sides.
P - 2L = 2W
Step 3: Divide both sides of the equation by 2 to solve for W.
(P - 2L) / 2 = W
Therefore, w is equal to (P - 2L) / 2.
