Question

Jim is three times as old as Allison. Two years ago, the sum of their age of 16. - Write a linear system

Answer 1

3j=s
(s-2)+(j-2) = 16?

Answer 2

let allison's age = x
jim's age = 3x

two years ago their sum is 16 so

jim's age 2 years ago = 3x - 2
allison's age 2 years ago = x - 2

so we'll have

(3x - 2) + (x - 2) = 16

got it?
