Problema Solution
five years ago, sara's age was half of the age she will be in 8 years. How old is she know?
Answer provided by our tutors
Let her age be x.
Five years ago, she was x-5 years old.
"five years ago, sara's age was half of the age she will be in 8 years"
means x - 5 = (1/2)(x-5 + 8)
So 2(x-5 ) = (x +3)
2x - 10 = x + 3
So x = 13
