(-\infty,3)\text{ }\cup(4,\infty)

Step-by-step explanation

Step 1

solve inequality 1


\begin{gathered} 2x-3>5\text{ } \\ \text{add 3 in both sides} \\ 2x-3+3>5+3 \\ 2x>8 \\ \text{divide both sides by 2} \\ (2x)/(2)>(8)/(2) \\ x>4 \end{gathered}

Step 2

Solve inequality 2


\begin{gathered} 3x-1<8 \\ \text{add 1 in both sides} \\ 3x-1+1<8+1 \\ 3x<9 \\ \text{divide both sides by 3} \\ (3x)/(3)<(9)/(3) \\ x<3 \end{gathered}

then the solution is


\begin{gathered} x>4\text{ or x}<3 \\ In\text{ interval denotation} \\ (-\infty,3)\text{ }\cup(4,\infty) \end{gathered}

I hope this helps you
