Question 883097: The sum of two numbers is 20. The difference is 6
Answer by algebrahouse.com(1659) (Show Source): You can put this solution on YOUR website!
x = one number
y = other number
x + y = 20 {sum of two numbers is 20}
x - y = 6 {their difference is 6}
----------
2x = 26 {added the two equations}
x = 13 {divided each side by 2}
x + y = 20 {first equation}
13 + y = 20 {substituted 13, in for x, into first equation}
y = 7 {subtracted 13 from each side}
13 and 7 are the two numbers
