Answer:
1. |×| = 5
x = 5
x = -5 (The equation has 2 Solution)
Solution: ×1 = -5, ×2 = 5
2. |×| = 17
× = 7
× = 17 (The equation has 2 Solution)
Solution: ×1 = -17, ×2 = 17
3.|× + 2| = 10
× +2 = 10
× +2 = -10 (The equation has 2 Solution)
Solution: ×1 = -12, ×2 = 8
4.|× - 9| = 8
× -9 = 8
× -9 = -8 (Solve the equations)
× = 17
× = 1 (the equations has 2 Solution)
Solution: ×1 = 1, ×2 = 17
5.|2× +1| = 3
|2| = 3 (Calculate the absolute value)
2 = 3 (check the equality)
