Garrett is 50 years younger than Mackenzie. 9 years ago, Mackenzie's age was 3 times Garrett's age. How old is Garrett now?

Answer 1

G= M -50

3(G-9) = M-9

3(M-50-9) =M-9

3M-3(59) = M-9

3M-M=-9 +177

2M= 168

M=168/2=84 years old for Mackenzie now

G =M-50= 34 years old for Garrett now

9 years ago they were 75 and 25

75 = 3 x 25
