Problema Solution
If you ate one half your sister's age and together your ages equal four less than five-thirds of her age, how old is your sister?
Answer provided by our tutors
let 'x' represent your sister's age, then x/2 represents your age
together your ages equal four less than five-thirds of her age:
x + x/2 = (5/3)x - 4
solving for 'x' we have:
x = 24
your sister is 24 years old
