Question 74
Choose a letter x, y, z, p etc...., wherever necessary, for the unknown (variable) and write the corresponding expressions for the given statement:
Write an equation whose solution is not a whole number.
The set of whole numbers is (0, 1, 2, 3, ...).
Consider the equation x+1=0.
Subtracting 1 from both sides of the equation, we get
x+1−1=0−1
⇒x=−1 (-1 is not a whole number.)
