Find three consecutive even intergers such that the sum of the smallest and twice the second is 20 more than the third

Answer 1

Find three consecutive even intergers such that the sum of the smallest and twice the second is 20 more than the third

Let the integers be x, x + 2, x + 4

x + 2(x + 2) - 20 = x + 4

x + 2x + 4 - 20 = x + 4

2x = 20

x = 10

x + 2 = 12

x + 4 = 14
