What is the value of 2(x+2) when x = 3?

Explanation:
Substituting the given value into the expression and applying the order of operations. Replace x with 3, so you have 2(3+2). Compute inside the parentheses first: 3+2 = 5. Then multiply by 2: 2 × 5 = 10. You can also see this through the distributive view: 2(x+2) = 2x + 4, and with x = 3 that becomes 6 + 4 = 10. The value is 10.
