Absolute Value Equation Game (Level 2)

Absolute Value Equation Game (Level 2)
This game is a level-up from Level 1. In this level, the absolute value bars |x| are not alone. You need is to isolate the bars by moving the outside numbers to the other side of the equation before you try to find the values for x.
Scroll down the page for a more detailed explanation.

How to Solve the Two Equation Types
Type 1: The Addition/Subtraction Model (|x| ± a = b)
You need to move the constant a to the other side using the opposite sign.
If you see |x| + 5 = 12: Subtract 5 from 12. You get |x| = 7.
If you see |x| - 3 = 10: Add 3 to 10. You get |x| = 13.

Type 2: The Multiplication Model (a|x| = b)
The number a is stuck to the bars. You must divide both sides by a.
If you see 3|x| = 15: Divide 15 by 3. You get |x| = 5.
If you see 2|x| = 0: Divide 0 by 2. You get |x| = 0

Reading the “Isolated” Result
Once you have the bars alone (|x| = number), look at that number to decide your answer:
Positive (e.g., 5): Select the positive and negative number (5 and -5).
Zero (0): Select only 0.
Negative (e.g., -4): Select No Solution.
 

Gameplay Steps

1. Calculate: Mentally isolate the bars.
   
2. Select: Click the buttons in the grid that match your final x values.
   Tip: If the isolated result is positive, you must pick two buttons.
   
3. Check: Hit “Check Solutions”.
   Green: Correct.
   Red: Incorrect
   
4. Repeat: Click “Next Equation”.
