Question

Combine the like terms to create an equivalent expression:
\large{4z-(-3z)}

Answer 1

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}.
