3n+9=6n+8+2n
Use the distributive property to multiply 3 by n+3.
3n+9=8n+8
Combine 6n and 2n to get 8n.
3n+9-8n=8
Subtract 8n from both sides.
-5n+9=8
Combine 3n and -8n to get -5n.
-5n=8-9
Subtract 9 from both sides.
-5n=-1
Subtract 9 from 8 to get -1.
n=\frac{-1}{-5}
Divide both sides by -5.
n=\frac{1}{5}
Fraction \frac{-1}{-5} can be simplified to \frac{1}{5} by removing the negative sign from both the numerator and the denominator.
