x+3+9x=0
Add 9x to both sides.
10x+3=0
Combine x and 9x to get 10x.
10x=-3
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-3}{10}
Divide both sides by 10.
x=-\frac{3}{10}
Fraction \frac{-3}{10} can be rewritten as -\frac{3}{10} by extracting the negative sign.
