Question

find three consecutive even numbers so that the sum of the first and third numbers is 22 less than three times the second number

Answer 1

let x = first even number
x+2 = consecutive even number
x+4 = next consecutive even number

x + x+ 4 = 3(x+2) - 22
2x + 4 = 3x + 6 - 22
22 + 4 - 6 = 3x - 2x
20 = x
x+2 = 22
x+ 4 = 24
