\begin{tabular}{l} Combine any like terms in the expression. If there are no like terms, rewrite the expression. \\ \( 9 g+4-9 g \) \\ Submit \\ \hline\end{tabular}

When you combine like terms in the expression \( 9g + 4 - 9g \), you'll notice that the \( 9g \) and the \( -9g \) cancel each other out. This leaves you with just the constant term, which is \( 4 \). So, the simplified expression is \( 4 \). It’s fun to think of it like balancing scales: the \( 9g \) on one side and the \( -9g \) on the other perfectly offset each other, leaving only the number 4 as the outcome!
