Question 1041180
{{{  3/11 - x/121 = -1/142 }}}
{{{ ( 11/11 )*( 3/11 ) - x/121 = -1/142 }}}
{{{ 33/121 - x/121 = -1/142 }}}
{{{ ( 33 - x ) / 121 = -1/142 }}}
Multiply both sides by {{{ 121*142 }}}
{{{ 142*( 33 - x ) = -121 }}}
{{{ 4686 - 142x = -121 }}}
{{{ 142x = 4686 + 121 }}}
{{{ 142x = 4807 }}}
{{{ x = 33.8521 }}}
-------------------
check:
{{{  3/11 - x/121 = -1/142 }}}
{{{ .27273 - .008264x = -.007042 }}}
{{{ .008264x = .27273 + .007042 }}}
{{{ .008264x = .279772 }}}
{{{ x = 33.8543 }}}
pretty close -error may be due to rounding off
