Expand.
\[3x-8x+10=-15x+30\]
Simplify \(3x-8x+10\) to \(-5x+10\).
\[-5x+10=-15x+30\]
Subtract \(10\) from both sides.
\[-5x=-15x+30-10\]
Simplify \(-15x+30-10\) to \(-15x+20\).
\[-5x=-15x+20\]
Add \(15x\) to both sides.
\[-5x+15x=20\]
Simplify \(-5x+15x\) to \(10x\).
\[10x=20\]
Divide both sides by \(10\).
\[x=\frac{20}{10}\]
Simplify \(\frac{20}{10}\) to \(2\).
\[x=2\]
x=2
