The sum of two numbers is 64, and the larger number is 3 less than 3 times the smaller number.
Find the smaller number. x = smaller number {large number is 3 less than 3 times the smaller number}3x - 3 = larger number x + 3x - 3 = 64 {the sum of the two numbers is 64} 4x - 3 = 64 {combined like terms} 4x = 67 {added 3 to each side} x = 16.75 {divided each side by 4} 16.75 is the smaller numberBy the way, 3x - 3 {larger number} = 3(16.75) - 3 {substituted 16.75, in for x, into 3x - 3} = 50.25 - 3 {multiplied 3 by 16.75} = 47.25 {subtracted} 47.25 is the larger numberAsk the House
