The product of two positive integers plus their sum is 95. The integers are relatively prime, and each is less than 20. What is the sum of the two integers?

Let the fist integer be x, the second is x+20

the product of the numbers is:

x (x+20)

the sum of the numbers is:

x+x+20=2x+20

the sum of the above operations will give us:

2x+20+x^2+20x=95

x^2+22x+20=95

this can be written as quadratic to be:

x^2+22x-75=0

solving the above we get:

x=3 and x=-25

but since the integers should be positive, then x=3

the second number is x+20=3+20=23

hence the numbers are:

3 and 23
