Question 796152
What you are possibly trying to show for help is this:

{{{(12+x)/(-4)=(4x-14)/3+4}}}


Use the simplest common denominator, "12", and multiply left member and right member by 12.  This will help to clear the fractions or rational terms.  The step will give you this:


{{{(12+x)*(-3)=4(4x-14)+48}}}
{{{-3x-36=16x-56+48}}}
{{{-3x-16x=36-56+48}}}
{{{-19x=-20+48}}}
{{{-19x=28}}}
{{{highlight(x=-28/19)}}}
