Problema Solution
Harry is 8 years older than jill. four years from now the sum of their ages will be 80. how old are harry and jill?
Answer provided by our tutors
Let
x = the age of Harry
y = the age of Jill
x = y + 8 (Harry is 8 years older than Jill)
x + 4 + y + 4 = 80 (four years from now the sum of their ages will be 80)
Lets solve the system equations
x = y + 8
x + 4 + y + 4 = 80
x = 40
y = 32
Harry is 40 years old and Jill is 32 years old.
