Question 710991
Let The tens digit = {{{ a }}}
Let the units digit = {{{ b }}}
given:
{{{ 10a + b - 36 = 10b + a }}}
{{{ 10a - a - 10b + b = 36 }}}
{{{ 9a - 9b = 36 }}}
{{{ 9*( a - b ) = 36 }}}
{{{ a - b = 4 }}}
Any number for which this is true works
check:
{{{ a = 9 }}}
{{{ b = 9 - 4 }}}
{{{ b = 5 }}}
{{{ 95 - 36 = 59 }}}
also
{{{ 84 -36 = 48 }}}
seems to work
