{{{7/y - 1/3 = 1/4}}}


First multiply both sides of the equation by the LCD, which is 12y:

{{{(12y)*7/y -(12y)* 1/3 = (12y)*1/4}}}


Divide out ALL the denominators:

{{{84 - 4y = 3y }}}


Add 4y to each side:

{{{84 - 4y +4y  = 3y + 4y}}}

{{{84 = 7y }}}


Divide both sides by 7:
{{{12 = y}}}


Check:  Substitute y= 12 in the origianl equation.
{{{7/12 - 1/3 = 1/4}}}
{{{7/12 - 4/12 = 3/12 }}}   It checks!
