Answer:

the solution is;


\mleft\lbrace x\mright|x<-4.5|\}

Given the inequality;


-5x-3>-3(x-2)

Let's simplify and collect the like terms;


\begin{gathered} -5x-3>-3x-3(-2) \\ -5x-3>-3x+6 \\ -5x+3x>6+3 \\ -2x>9 \\ \text{dividing both sides by -2;} \\ (-2x)/(-2)<(9)/(-2) \\ x<-4.5 \end{gathered}

Note that when you divide an inequality through by a negative number, the inequality sign will change.

Therefore, the solution is;


\mleft\lbrace x\mright|x<-4.5|\}
