Question

The sum of the present ages of two friends is 23 years, five years ago product of their ages was 42. Find
their ages 5 years ​hence

Answer 1

Answer:

their ages 5 years hence will be 18 and 15

Step-by-step explanation:

x+(23-x)=23

(x-5)(23-x-5)=42

-x^+18x+5x-90=40

x^-23x+130=0

x^-10x-13x+130=0

by factoring

x (x'10)-13 (x-10)

x-10=0. x-13=0

x=10 x=13

the ages 5 years hence is if x=13

x=18 and the other is 15
