To solve for the inequality, we need to get x by itself and then simplify if needed.
Remember: What you do to one side of the equation you must apply it to the other side as well (unless it is using the distributive property).
10x +18 < -2
Our first task: Get x on one side (alone).
To get 10x by itself, subtract 18 from both sides.
18 -18 = 0
-2 -18 = -20 (When subtracting negatives from a negative, you're just adding with a negative number).
The inequality now is:
10x < -20
Divide both sides by 10 to find x.
10x/10 = x
-20/10 = -2.
X < -2
I hope this helps!
