Multiple Choice

Evaluate 2x + 5 when x = 3.

Explanation:
Evaluating a linear expression by substitution: replace x with 3 and follow the order of operations. Double x to get 2×3 = 6, then add 5 to get 11. So the result is 11. The other numbers would come from either using a different x or changing the amount you add, which isn’t what the expression specifies here.
