Write an equation whose solution is not a whole number.
x + 1 = 0
Idea: A whole number is one of 0, 1, 2, 3, … (no negatives).
Given equation:
(x + 1 = 0)
Step 1: Move 1 to the other side (subtract 1 from both sides):
(x + 1 - 1 = 0 - 1)
Step 2: Simplify:
(x = -1)
Check (put (x = -1) back):
(-1 + 1 = 0) ✓
Conclusion: The solution is (-1), and (-1) is not a whole number. So this equation’s solution is not a whole number.
