Answer

Yes, it does make sense.

Work Step by Step

Consider the given equation. $-2x+5\ge 13$ Solve the above equation. $\begin{align} & -2x+5\ge 13 \\ & -2x\ge 13-5 \\ & x\le \frac{8}{-2} \\ & x\le -4 \end{align}$ Now, the above solution shows that the value of x is less than or equal to$-4$. So, this concludes that$-4$ is the greatest integer in the solution set. Thus, the given statement does make sense.
