5a+9=-5a
Combine 3a and -8a to get -5a.
5a+9+5a=0
Add 5a to both sides.
10a+9=0
Combine 5a and 5a to get 10a.
10a=-9
Subtract 9 from both sides. Anything subtracted from zero gives its negation.
a=\frac{-9}{10}
Divide both sides by 10.
a=-\frac{9}{10}
Fraction \frac{-9}{10} can be rewritten as -\frac{9}{10} by extracting the negative sign.
