    Look at it like it is an equation. In order to find x, you need to get x by itself. So to do that the first thing you would do is get rid of the 9, by adding 9 to both sides. (-2/5x-9) + 9 < (9/10) + 9 Simplify, now you have -2/5x < 9 9/10 In order to get rid of -2/5, and get x by itself, you would need to multiply both sides by the denominator, which is 5. (-2/5x) *5 < (9 9/10) * 5 Simplify, now you have -2x < 40 9/10 Now, the last step is just divide both sides by -2! Keep in mind that when you divide by a negative number, the inequality sign flips So your final answer is: x > -20 9/10
