Sam is 3 times as old as rob. if 15 is subtracted from sam's age and 13 is added to rob's age, their ages will be equal. how old is each now?

Sam is 42 years old and Rob is 14 years old.

Step-by-step explanation:

x = Rob's age

3x = Sam's age

3x - 15 = x + 13

3x - x = 13 + 15

2x = 28

x = 14

Check:  If you subtract 15 from Sam's age and add 13 to Rob's age they would both be 27.

3(14) - 15 = 14 + 13

42 - 15 = 27

27 = 27
