Since the numbers are consecutive whole numbers, you can set up the following equation to find their individual ages:
[tex]x + (x + 1) + (x + 2) = 111[/tex]
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.
[tex]x + x + x = 3x[/tex]
[tex]1 + 2 = 3[/tex]
[tex]3x + 3 = 111[/tex]
Subtract 3 from both sides.
[tex]3x = 108[/tex]
Divide both sides by 3 to get x by itself.
[tex]x = 36[/tex]
(x+1) is used to represent Taylor's age, so plug in your x value.
[tex]36 + 1 = 37[/tex]
Taylor's age is 37.
