The sum of two numbers is 40. The larger number is 20 more than the smaller number. What are the two numbers?
x = smaller number
x + 20 = larger number x + x + 20 = 40 {sum of two numbers is 40} 2x + 20 = 40 {combined like terms} 2x = 20 {subtracted 20 from each side} x = 10 {divided each side by 2} x + 20 = 30 {substituted 10 back into x + 20} 10 and 30 are the two numbers See more number problem examples here or Ask the House
