Explain 4X 5A8883

1. To explain where the $4x$ came from in step 5, we need to look at the previous steps in the problem. 2. Usually, $4x$ appears when you multiply or combine like terms involving $x$. 3. For example, if you had $2x + 2x$, combining like terms gives $4x$. 4. Alternatively, if you multiplied $2 \times 2x$, you also get $4x$. 5. Without the exact previous steps, the most common reason for $4x$ is combining or multiplying terms involving $x$. 6. If you provide the full step 4 or the equation, I can give a precise explanation.
