You solve an inequality by treating the greater than and less than like a equal sign, an example is 6x + 15 is less than 9. You could see it as 6x + 15 = 9, so you minus 15 from 9, making it -6. Now, 6x = -6. Divide by 6, and you get x is less than -1. After this, x can equal anything that is less than -1. You can make x equal -2, now you can check the problem: 6x + 15 is less than 9

6(-2) + 15 is less than 9

-12 + 15 is less than 9

3 is less than 9

TRUE!!! This is a true statement because 3 is less than 9. Good luck in the world of Math!
