Find two numbers with a sum of 66 and a difference of 116. x = one number
y = other number x + y = 66 {sum is 66} x  y = 116 {difference is 116}  2x = 182 {added the two equations together} x = 91 {divided both sides by 2} x + y = 66 {top equation} 91 + y = 66 {substituted 91, in for x, into top equation} y = 25 {added 91 to both sides} Two numbers are 91 and 25 *To check* 91 + 25 = 66 {sum is 66} 91  25 = 116 {difference is 116} © Algebra House
