What is a problem using combining like terms that equal?

Combining like terms is a common algebraic practice that simplifies expressions by consolidating terms with the same variable and exponent. A problem might involve the expression (3x + 2x - 5 + 7). By combining the like terms, you would add (3x) and (2x) to get (5x), and combine (-5) and (7) to get (2), resulting in the simplified expression (5x + 2). This process helps streamline calculations and makes it easier to solve equations.
