p=2l+2w solve for l
p=2l+2w solve for l
2l = p - 2w
l = (p - 2w)/2
I just want to add that whenever they ask you to solve for a letter, any letter, it means to isolate the letter just like Ms. Sue easily did.
Do you see that l has been isolated on the left side of the equation?
This is very important to keep in mind in any math course.
Also, it does NOT matter on which side of the equation the variable is isolated.
Got it?
To solve the equation p = 2l + 2w for l, you need to isolate the variable l on one side of the equation.
Step 1: Start with the given equation: p = 2l + 2w
Step 2: Now, subtract 2w from both sides of the equation to isolate the term containing l:
p - 2w = 2l + 2w - 2w
Simplifying the equation, you have:
p - 2w = 2l
Step 3: Divide both sides of the equation by 2 to solve for l:
(p - 2w) / 2 = (2l) / 2
Simplifying further, you get:
(p - 2w) / 2 = l
So, the expression (p - 2w) / 2 gives the value of l when you solve the equation p = 2l + 2w.
