You can put this solution on YOUR website! Ray is 15 years older than Sam and Sam is 12 years older than Bart their ages 42 years how old is each
Lets say Bart is x years old, then Sam would be x+12 years old, and Ray would be x+12+15 years old, add up all ages and solve for x
x+x+12+x+12+15=42
3x+39=45
3x=6
x=2
so Bart is 2 years old
Sam is 2+12=14 years old
Ray is 2+12+15=29 years old
