Verified step by step guidance

Start with the compound inequality: $-6 < 2x - 4 < 4$.

Add 4 to all three parts of the inequality to isolate the term with $x$: $-6 + 4 < 2x - 4 + 4 < 4 + 4$, which simplifies to $-2 < 2x < 8$.

Divide all parts of the inequality by 2 to solve for $x$: $\frac{-2}{2} < \frac{2x}{2} < \frac{8}{2}$, which simplifies to $-1 < x < 4$.

Interpret the solution: $x$ is greater than $-1$ and less than \$4$, so $x$ lies between $-1$ and $4$ but does not include $-1$ or $4$ themselves.

Graph the solution on the number line by drawing an open interval (parentheses) from $-1$ to \$4$, indicating that these endpoints are not included.
