Hi,
For this question, you need to treat the inequality like it was indeed an equals sign.
The first step is to move the +18 to the right hand side of the inequality by subtracting 18 from both sides. You should get the following:
-8x > 40
Now, remember we need to divide by -8 to undo the multiplication operation that's being shown here. So, we need to divide both sides by -8 which in turn, makes us flip the inequality sign to get:
FINAL ANSWER:
x < - 5
REMEMBER: Whenever you DIVIDE or MULTIPLY by a negative number in an inequality, you MUST always switch the direction of the inequality sign!!!!
I hope that helps you out! Please let me know if you have any other questions!
Sincerely,
Andrew

Negate the whole thing, to get:
8x -18 < 22. Add 18 to each side to get:
8x < 40. Divide through by 8 to get:
x < 5. Done.

-8x > -22 -18
-8x > -40 divided by -8
x < 5

-8x+18>-22
-8x > -40 (subtracted 18 from both sides)
x < 5 (reverse sign of inequality when you divide by a negative number)
