Example:
Mike is 7 years younger than Jill. Together, there ages add up to 19. Find both their ages.
Solution:
Let x = Jill's age
Then x - 7 = Mike's age
Their ages add up to 19
x + (x-7) = 19
x + x - 7 = 19
2x - 7 = 19
2x - 7 + 7 = 19 + 7
2x = 26
x = 13
x - 7 = 13 - 7 = 6
Verification: x + (x-7) = 13 + (13-7) = 13 + 6 = 19
Jill is 13 and Mike is 6 year old.

Example:
Harold's age is four times the sum of the ages of his two daughters. Six years hence, his age will be double the sum of their ages. Find Harold's age.
Solution:
Let the sum of the ages of his two daughter be 'x' years.
Harold's age = 4x
Six years hence, the sum of the ages of the two daughters = x + 6 + 6
= x + 12
Harold's age = 4x + 6
4x + 6 = 2(x + 12)
4x + 6 = 2x + 24
2x = 24 - 6 = 18
x = 9.
Harold's age = 4x = 36 years
