Form an expression that is equivalent to −x+(−3x)+12−9

Question

.____ + ____

Answer 1

To simplify the expression \(-x + (-3x) + 12 - 9\), let's first combine like terms:

1. Combine the \(x\) terms: \(-x + (-3x) = -x - 3x = -4x\)

2. Combine the constant terms: \(12 - 9 = 3\)

Now, we put these results together:

\[ -x + (-3x) + 12 - 9 = -4x + 3 \]

To express this in the format requested (____ + ____), we can rewrite it as:

\[ -4x + 3 = -4x + 3 \]

Thus, the equivalent expression can be filled in as:

\[ -4x + 3 \]

So, the final answer is: −4x + 3.
