Question

Combine like terms. Then, solve for x.
6x – 5 – 4x = –15
[?]x – 5 = –15 (6x + 4x goes in the [?])
x = [?]

Answer 1

Let's start by combining like terms in the equation \(6x - 5 - 4x = -15\).

Combine the \(6x\) and \(-4x\):

\[
(6x - 4x) - 5 = -15
\]

This simplifies to:

\[
2x - 5 = -15
\]

Now, we need to isolate \(x\). First, add 5 to both sides of the equation:

\[
2x = -15 + 5
\]

\[
2x = -10
\]

Next, divide both sides by 2:

\[
x = \frac{-10}{2}
\]

\[
x = -5
\]

Now, filling in the answers for your format:

1. \[?]x - 5 = -15 → 2x - 5 = -15\]
2. \(x = -5\)

So, the values are:

\[? = 2\]
\[x = -5\]
