Regroup terms.
\[3p-3p\times 4+7pg=12-\]
Simplify \(3p\times 4\) to \(12p\).
\[3p-12p+7pg=12-\]
Simplify \(3p-12p+7pg\) to \(-9p+7pg\).
\[-9p+7pg=12-\]
Factor out the common term \(p\).
\[-p(9-7g)=12-\]
Divide both sides by \(-p\).
\[9-7g=-\frac{12-}{p}\]
Subtract \(9\) from both sides.
\[-7g=-\frac{12-}{p}-9\]
Divide both sides by \(-7\).
\[g=-\frac{-\frac{12-}{p}-9}{7}\]
Simplify \(\frac{-\frac{12-}{p}-9}{7}\) to \(-\frac{\frac{12-}{p}}{7}-\frac{9}{7}\).
\[g=-(-\frac{\frac{12-}{p}}{7}-\frac{9}{7})\]
Simplify \(\frac{\frac{12-}{p}}{7}\) to \(\frac{12-}{7p}\).
\[g=-(-\frac{12-}{7p}-\frac{9}{7})\]
Remove parentheses.
\[g=\frac{12-}{7p}+\frac{9}{7}\]
g=(12-)/(7*p)+9/7
