When an inequality is multiplied or divided by a negative number, the inequality symbol must be flipped. This has not been done in the last step. $\begin{aligned} \text{-}4x < 8 \\ x < \text{-}2 \end{aligned}$ Ron-Jon divided both sides with $\text{-}4$ but he forgot to flip the sign.

Let's start from the beginning. Remember the rule for inequalities when multiplying or dividing by a negative.

$13x\lt 17x+8$

SubIneq$\text{LHS}-17x\lt\text{RHS}-17x$

$\text{-}4x\lt 8$

DivNegIneqDivide by $\text{-}4$ and flip inequality sign

$x\gt \text{-}2$
