The formula for the perimeter of a rectangle can be expressed in more than one way. One way is P=2 (l + w). Discuss how you could manipulate this equation to isolate l. Write down the steps and include and explanation of each step. Is there more than one way to do this? Explain

First you would divide by 2 in both sides

P/2 = l + w

Then you would subtract w from both sides

P/2 - w = l

This is the easiest method do isolate l

You can also distribute the 2 to (l + w) first

P = 2l + 2w

Then subtract 2w from both sides

P - 2w = 2l

Then you would divide by 2

(P - 2w) / 2 = l

P/2 - w = l
