Question 676593: Chris is 3 years older than Jacob. Nathan is eighteen years old. Two years ago the sum of all their ages was 59 years old. How old is Jacob?
You can put this solution on YOUR website! Let x = Jacob's current age
Let x+3 = Chris's current age
18 = Nathan's current age
Jacob's age 2 years ago is x-2
Chris's age 2 years ago is x+3-2 which is x+1
Nathan's age 2 years ago is 18-2 which is 16
two years ago all their ages added up to 59 years old
so our equation is:
x-2+x+1+16=59
2x+15=59
2x=44
x=22
Jacob is 22 years old
plug the answer into the equation to check work
