Question. 74

Write an equation whose solution is not a whole number.

Answer:

x + 1 = 0

Detailed Answer with Explanation:

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.
