6b+9=-2\left(3+1\right)
Multiply both sides of the equation by 6, the least common multiple of 2,3.
6b+9=-2\times 4
Add 3 and 1 to get 4.
6b+9=-8
Multiply -2 and 4 to get -8.
6b=-8-9
Subtract 9 from both sides.
6b=-17
Subtract 9 from -8 to get -17.
b=\frac{-17}{6}
Divide both sides by 6.
b=-\frac{17}{6}
Fraction \frac{-17}{6} can be rewritten as -\frac{17}{6} by extracting the negative sign.
