Combine the like terms to create an equivalent expression:

\large{4z-(-3z)}

1 answer

To combine like terms, we need to perform the operation indicated by the subtraction sign. In this case, we need to distribute the negative sign to the terms inside the parentheses:

\begin{align*}
4z - (-3z) &= 4z + 3z
\end{align*}

Now, we can combine the like terms by adding the coefficients:

\begin{align*}
4z + 3z &= \boxed{7z}
\end{align*}

So, the equivalent expression is \boxed{7z}.
