-------------------
K = Mark's age now
M = Mia's age now
---
K-2 = 3(M-2)
K = 2M
---
Sub for K
2M-2 = 3(M-2) = 3M-6
Add 6
2M+4 = 3M
Subtract 2M
4 = M
M = 4

let x=Mia's age this year
2x==Mark's age this year
2 yrs ago:
x-2=mia's age
2x-2=Mark's age
2x-2=3(x-2)
2x-2=3x-6
x=4
Mia's age=4
Mark's age=8
