Solve $LaTeX: \displaystyle 3 x + 2 < -9$ . Write the solution in interval notation.

Isolating $LaTeX: \displaystyle x$ gives $LaTeX: \displaystyle 3 x<-11$ . Dividing off the $LaTeX: \displaystyle x$ coefficient gives $LaTeX: \displaystyle x<0$ . The solution is $LaTeX: \displaystyle \left(-\infty, - \frac{11}{3}\right)$
