Question: what is p 2l 2w solve for w?
Answer: Solve P = 2L + 2w for w This is the formula for the perimeter P of a rectangle with length L and width w. If they'd asked me to solve 3 = 2 + 2w for w, I'd have subtracted the "free" 2 over to the left-hand side, and then divided through by the 2 that's multiplied on the variable.
