Mark, taylor, & brian's ages are consecutive whole numbers. mark is the youngest, and brian is the oldest. the sum of their ages is 111. how old is taylor?

Since the numbers are consecutive whole numbers, you can set up the following equation to find their individual ages:



x will represent Mark's age, (x+1) will represent Taylor's age, and (x+2) will represent Brian's age.

Simplify the equation by combining like terms. 





Subtract 3 from both sides.



Divide both sides by 3 to get x by itself.



(x+1) is used to represent Taylor's age, so plug in your x value.



Taylor's age is 37.
