Question

which terms are like terms in the expression $5x + 9 + (-7x)$? choose all that apply. $5x$ $9$ $-7x$

Explanation:

Like terms are terms with the same variable (or no variable for constants). In the expression \(5x + 9 + (-7x)\), \(5x\) and \(-7x\) both have the variable \(x\), so they are like terms. The term \(9\) is a constant and has no variable, so it is not like terms with \(5x\) or \(-7x\).

Answer:

\(5x\), \(-7x\)
