Here is another example:
X + 8 < 20
You find the solution to that inequality this way:
X + 8 < 20 ---- start with the example
X + 8 - 8 < 20 - 8 ----- subtract 8 from each side
X < 12 ---- gives you the solution you're looking for
Note:
A way to find a different inequality with that solution is to start with that solution:
X < 12
Then, do a mathematical operation to each side, such as "subtract 3":
X - 3 < 12 - 3
Simplify the resulting inequality:
X - 3 < 9
Which gives you an inequality with the solution you're looking for.
