Question 540744
Is this {{{ ( x+2 )/6 - (x-2)/12 = 1/12 }}} ?
You should use parentheses to group terms
Multiply both sides by {{{12}}}
{{{ 2*( x + 2 ) - ( x - 2 ) = 1 }}}
{{{ 2x + 4 - x + 2 = 1 }}}
{{{ x + 6 = 1 }}}
{{{ x = -5 }}}
---------
Check answer:
{{{ ( x+2 )/6 - (x-2)/12 = 1/12 }}}
{{{ ( -5+2 )/6 - (-5-2)/12 = 1/12 }}
{{{ -3/6 -(-7)/12 = 1/12 }}}
{{{ -6/12 + 7/12 = 1/12 }}}
{{{ 1/12 = 1/12 }}}
OK
