The sum of three consecutive even integers is 126. Let x represent the first integer, x + 2 represent the second integer, and x + 4 represent the third integer.

Which equation can be used to find the first integer?

2x + 6 = 126

3x = 2x + 6

3x + 6 = 126

3x + 126 = 2x + 6

    We have that (x) + (x+2) + (x+4) = 126 so 3x + 6 = 126 can be used to find the first integer.

    3x + 6 = 126

    3x = 120

    x = 40

    The numbers are 40, 42, 44
