If x = y + 3 and y = 5, then what is the value of x?

  1. 5

  2. 7

  3. 8

  4. 10

The correct answer is: 8

To solve this problem, plug in the given value of y (5) into the first equation given, x = y + 3. This yields x = 5 + 3 = 8. Therefore, the value of x is 8. The other answer options are incorrect because they either do not account for the additional 3 in the equation (7) or they use the incorrect value of y (10 and 5, respectively).
