2x+%2B+5+%3C+8x+%2B+3

Do just as you would for an equality.
2x%2B5-2x%3C8x%2B3-2x
2x-2x%2B5%3C8x-2x%2B3
5%3C8x%2B3
5-3%3C8x%2B3-3
2%3C8x
1%2F4%3Cx

You only need to watch for any step which multiplies or divides by a negative number, meaning, a negative VALUE. Those steps require switching the order of the inequality symbol. That kind of operation did not occur in this example.
