\begin{gathered} 2(2z-4)=3(z+5) \\ 4z-8=3z+15 \\ 4z-3z=15+8 \\ z=23 \end{gathered}
\begin{gathered} \text{first step, do the multiplication. That is, multiply by 2 the left side and multiply by 3 the right side, hence} \\ 4z-8=3z+15 \\ \text{Now, the term 3z is going to the left side as -3z and} \\ -8\text{ is going to the right side as +8} \\ \text{Next, add 4z-3z and 15 plus 8} \\ \text{therefore, you w}il\text{ have} \\ 4z-3z\text{ which is equal to 1z and} \\ 15+8\text{ =23 on the right side} \end{gathered}
