Age Difference Calculator
Let be 's age and be 's age. We have the following equations
= - 12 ←younger means we subtract
+ = 60
Plugging in (1) to (2), we get:
( - 12) + = 60
Grouping like terms, we get:
2 - 12 = 60
Add 12 to each side:
2 - 12 + 12 = 60 + 12
Cancelling the 12 on the left side, we get:
2 = 72
Divide each side by 2
2
2
=
72
2
Cancelling the 2 on the left side, we get:
=
36
←'s age
Calculate 's age:
Plugging = 36 into equation (1), we get
= 36 - 12
=
24
←'s age
