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.
