Problema Solution
two numbers add to 25, if the large is four times the smaller,find the two numbers
Answer provided by our tutors
let the numbers be 'x' and 'y' and we can assume x > y then
x and y add to 25 that is
x + y = 25
the larger is four times the smaller
x = 4*y
by solving the system of equations
x + y = 25
x = 4*y
we find
x =20
y = 5
the numbers are 20 and 5.
