Question 111651
{{{(4/7)p-6=(2/7)p+12}}}...........move {{{(2/7)p}}} to the left and {{{-6}}} to the right

{{{(4/7)p-(2/7)p=12+6}}}...........on the left side, least common denominator is {{{7}}}

{{{(4p/7)-(2/7)p=18}}}...........


{{{2p/7 = 18}}}…………. divide both sides by {{{2}}}, 

{{{2p/(2*7) =  18/2}}}………….

{{{ p/7 =  9}}}………….multiply both sides by {{{7}}}

{{{ (p/7)7 =  9*7}}}………….

{{{ p = 63}}}………….
