\pi x+3+9x=0
Add 9x to both sides.
\pi x+9x=-3
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
\left(\pi +9\right)x=-3
Combine all terms containing x.
\frac{\left(\pi +9\right)x}{\pi +9}=-\frac{3}{\pi +9}
Divide both sides by \pi +9.
x=-\frac{3}{\pi +9}
Dividing by \pi +9 undoes the multiplication by \pi +9.
