\[48x-16-27x-9=x+55\]
Simplify \(48x-16-27x-9\) to \(21x-25\).
\[21x-25=x+55\]
Add \(25\) to both sides.
\[21x=x+55+25\]
Simplify \(x+55+25\) to \(x+80\).
\[21x=x+80\]
Subtract \(x\) from both sides.
\[21x-x=80\]
Simplify \(21x-x\) to \(20x\).
\[20x=80\]
Divide both sides by \(20\).
\[x=\frac{80}{20}\]
Simplify \(\frac{80}{20}\) to \(4\).
\[x=4\]
x=4
