Question 122349
{{{p/3+7=12-2p/3}}}
The first thing to do is rearrange the equation so that all the terms with p in them are on one side of the = sign, and everything else is on the other.
Start by adding 2p/3to each side of the equation:
{{{2p/3+p/3+7=12-2p/3+2p/3}}}
Simplify the "p" terms:
{{{3p/3+7=12}}}
Next, add -7 to each side of the equation:
{{{3p/3+7-7=12-7}}}
Simplify:
{{{highlight(p=5)}}}
