Question

If a and b are positive integers, then the solution of the equation ax = b has to be always ______.

Options

• positive

• negative

• one

• zero

Answer 1

If a and b are positive integers, then the solution of the equation ax = b has to be always positive.

Explanation:

If ax = b, then `x = b/a`

Since, a and b are positive integers.

So, `b/a` is also positive integer.

Hence, the solution of the given equation has to be always positive.
