In the original number let the unit place by x
then the tens place is 2x, (obviously x < 5)
then the number in terms of its value is
10(2x) + x
and the number reversed is 10x + 2x
the difference between these two is 36, just translate this into Math.
10(2x) + x - (10x + 2x) = 36
solve for x
then the tens place is 2x, (obviously x < 5)
then the number in terms of its value is
10(2x) + x
and the number reversed is 10x + 2x
the difference between these two is 36, just translate this into Math.
10(2x) + x - (10x + 2x) = 36
solve for x
