Step-by-step explanation:
Smallest Integer = 2x - 2
Middle integer = 2x
Largest integer = 2x + 2
All three are every
3(2x - 2) = 2(2x + 2)
6x - 6 = 4x + 4 Add 6 to both sides
6x = 4x + 6 + 4 Combine
6x = 4x + 10 Subtract 4x from both sides
6x-4x = 10 Combine
2x = 10 Divide by 2
x = 10/2
x = 5
2x - 2 = 2*5 - 2 = 82x = 102x+2 123*8 = 2*12
24 = 24
So the answers are correct.
