You can put this solution on YOUR website! Find all the two-digit whole numbers (greater than zero) such that the difference between the whole number and the product of its digits is 12
:
Let x = 10's digit
Let y = units digit
:
Write an equation for what it says:
:
(10x + y) - xy = 12
y - xy = 12 - 10x
y(1 - x) = 12 - 10x
y =
:
Use the equation, to find y
x | y | no.|xy
---------------
2 | 8 | 28, 16
3 | 9 | 39, 27
and that's it
