Question

Which statement correctly describes the cancellation law in multiplication of whole numbers?

विकल्प

• If a + x = b + x, then a = b

• If a × x = b × x and x ≠ 0, then a = b

• If a − x = b − x, then a = b

• If a ÷ x = b ÷ x, then a = b

Answer 1

If a × x = b × x and x ≠ 0, then a = b

Explanation:

The cancellation law for multiplication allows cancelling a common non-zero factor from both sides of an equation.
