Jason is three times as old as Bill. The sum of their ages is 60. If the variable x represents Jason’s age and the variable y represents Bill’s age, which linear system can be used to solve for their ages?

• 3x = y

  3x + y = 60

• 3x = y

  x + y = 60

• x = 3y

  x + 3y = 60

• x = 3y

  x + y = 60
