Final answer:
To simplify the expression (5x + 10)+(-7x + 4), combine like terms to get -2x + 14.
Step-by-step explanation:
To simplify the expression (5x + 10)+(-7x + 4), we need to combine like terms. Like terms are terms that have the same variable and exponent. In this case, the like terms are the x terms (5x and -7x) and the constant terms (10 and 4). Combining the like terms gives us: 5x + (-7x) + 10 + 4. Simplifying further, we get: -2x + 14. Therefore, the expression (5x + 10)+(-7x + 4) is equivalent to -2x + 14.
