Final answer:
The expression x+5+2x+2 can be simplified by combining like terms. The simplified expression is 3x + 7.
Step-by-step explanation:
The expression equivalent to x+5+2x+2 can be simplified by combining like terms. Like terms are terms that have the same variables raised to the same exponent. In this expression, we have terms with x and numbers without variables. First, let's combine the terms with x: x + 2x = 3x. Next, let's combine the numbers without variables: 5 + 2 = 7. Therefore, the simplified expression is 3x + 7.
