Problema Solution
If the product of two postiive numbers is fifty four, and one number is three greater than the other, what are the two numbers?
Answer provided by our tutors
let 'x' and 'y' be the numbers, x>0, y>0
the product of two postiive numbers is 54
x*y = 54
one number is 3 greater than the other
y = x + 3
lets plug the value for y in x*y = 54 we get
x*(x + 3) = 54
by solving equation we find and consider only the positive solutions
