Question

write an expression that is equivalent to $-3x - 9 + 15 - 2x$.
$-3x - 9 + 15 - 2x = \square x +?$

Explanation:

Step1: Combine like terms for x

We have \(-3x\) and \(-2x\). Combining them: \(-3x - 2x = (-3 - 2)x = -5x\)

Step2: Combine constant terms

We have \(-9\) and \(+15\). Combining them: \(-9 + 15 = 6\)

Step3: Form the equivalent expression

Putting the combined terms together, we get \(-5x + 6\)

Answer:

\(-5\) \(x + 6\) (So the first box is \(-5\) and the second box is \(6\))
