You solve an inequality as if it were an equation!
For example, 2y + 5 < 13
- 5 -5
Subtract 5 from both sides, and you are left with:
2y < 8
Divide both sides by 2, and you are left with:
y < 4
Now since you still don’t have a definite answer, y could equal lots things, right? You show that by putting the answer on a number line.
What you add today is circle the number on the number line, and decide to fill it in or leave it open. Filled in means it can equal that number, open means it can’t, and you find that out from the inequality sign.
For example, y < 4 looks like <---------------------->
4
The left side is darker because of “less than” and the dot above the 4 is open because your value cannot equal 4.
If you had less than or equal to, you would have had to close the circle because y could be 4.
