You should come up with the following notation for the unknown numbers, such that: x,y

The problem provides two relations between the numbers, such that:

`x*y = 892143`

`x = 7y`

Replacing 7y for x in equation `x*y = 892143` yields:

`7y*y = 892143 `

Dividing by 7 both sides, yields:

`y^2 = 127449 => y_(1,2) = +-sqrt127449 => y_(1,2) = +-357`

`x_1 = 2499`

**Since the positive values follows the condition imposed by the problem, hence, evaluating the numbers yields **`x = 2499, y = 357.`
