Question

In two or more complete sentences describe the process you followed while isolating the variable w in the equation P=2(l+w)

Answer 1

We are given the following equation in which we are supposed to isolate the variable w by making it the subject of the equation and describe the process in two or more sentences:

`P=2(l+w)`.

Firstly, we will multiply 2 within the parenthesis to get
`P=2l+2w`.

Next, we will subtract the term '2l' from both sides of the equation to get
`P-2l=2w`.

Then, divide both sides of the equation by 2 to isolate w to get
`(P-2l)/(2) =w`.
