Answer:

One solution.

Step-by-step explanation:

Let us try to solve the equation and see how many solutions it has.

The first step in solving the equation is to first simplify both the right-hand and the left-hand sides. This means adding all the like terms.


\begin{gathered} 6z−3z−7=−2+3 \\ \Rightarrow3z-7=1 \end{gathered}

Next, we add 7 to both sides. This gives


3x-7+7=1+7
3x=8

dividing both sides by 3 gives


\boxed{z=8/3.}

which is exactly one solution!

Therefore, our equation had one solution.
