If x represents an even integer, which expression also represents an even integer? 1. 2x+1 2. 2x 3. x+1 4. x-1 Arbitrarily select an even number for x and substitute. I will arbitrarily select the even number 8. I could choose 6 or 10 or 74 or 2 or 50 or 2000000. But I'll stick with 8. So let x = 8 Substitute 8 for x in the choices till you find it: 1. 2x+1 2. 2x 3. x+1 4. x-1 becomes 1. 2x+1 = 2(8)+1 = 16+1 = 17, nope that's an odd number 2. 2x = 2(8) = 16, yep that's an even number (so that's the correct choice, but let's check the other ones anyway, to show that they are not even) 3. x+1 = (8)+1 = 9, nope that's an odd number 4. x-1 = (8)-1 = 7, nope that's an odd number.
