To combine like terms in (5x + 3) - (2x - 7), you first distribute the negative sign through the parentheses to change the signs inside the second set of parentheses. This results in (5x + 3) - 2x + 7. Then, you combine like terms, which are the terms involving x. So, 5x - 2x equals 3x, and 3 + 7 equals 10. Therefore, the simplified expression is 3x + 10.
