1. The problem is to identify where the term $8x$ was applied in the previous question. 2. Typically, $8x$ would be a term in an algebraic expression or equation. 3. To understand where $8x$ was applied, we need to look at the expression or equation it was part of. 4. For example, if the expression was $4x + 8x$, then $8x$ was added to $4x$. 5. If the expression was $8x(2x + 3)$, then $8x$ was multiplied by the binomial $(2x + 3)$. 6. Without the exact previous expression, the general rule is that $8x$ is either added, subtracted, multiplied, or divided with other terms. 7. Please provide the previous expression or equation for a precise explanation.
