The first number: x The second number: x + 3 The third number 2 * x - 11 Sum of all numbers: 65 We can write it down as an equation: 65 = x + 3 + x + 2x - 11 65 = 4x + 3 - 11 65 = 4x - 8                         / + 8 (both sides) 73 = 4x                             / ÷ 6 (both sides_ x = 18,25 Doublecheck: The first number: 18,25 The second number 18,25 + 3 = 21,25 The third number: 2 * 18,25 - 11 = 36,5 - 11 = 25,5 Sum of all numbers: 18,25 + 21,25 + 25,25 = 65, so it's correct :)
