Question 1109775
{{{ ( 5*7.7 )/x = ( 5 - x )/x }}}
{{{ 38.5/x = ( 5-x )/x }}}
If I do the division on the right side, I get:
{{{ 38.5/x = -1 + 5/x }}}
Multiply both sides by {{{ x }}}
{{{ 38.5 = -x + 5 }}}
{{{ x = 5 - 38.5 }}}
{{{ x = -33.5  }}}
------------------
check:
{{{ 38.5/(-33.5) = ( 5 -(-33.5) ) / (-33.5) }}}
Multiply both sides by {{{ -33.5 }}}
{{{ 38.5 = 5 + 33.5 }}}
{{{ 38.5 = 38.5 }}}
OK
