Age Difference Calculator
By Andrew Mckinney
Let 1 be 's age and be 's age.
We have the following equations
alvin is 12 years younger than elga. the sum of their ages is 60. what is elgas age?
- 1 = - 12 ←younger means we subtract
- 1 + = 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
Cancelling the 2 on the left side, we get:
= 36 ←'s age
Calculate 's age:
Plugging = 36 into equation (1), we get
1 = 36 - 12
1 = 24 ←'s age
Final Answer:
1 = 24 and = 36
You have 1 free calculations remaining
What is the Answer?
1 = 24 and = 36
