Given the following formula, solve for l.

Option C

l = (P - 2b)/2

Step-by-step explanation:

From P = 2(l + b)

Divide both sides by 2;

P/2 = 2(l + b)/2

P/2 = l + b

l + b = P/2

Make l the subject of formula;

l = (P/2) - b

l = (P - 2b)/2

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
