Question

1. simplify -9 + (-\frac{1}{3}y) + 6 - \frac{4}{3}y.

Explanation:

Step1: Remove parentheses

$-9 - \frac{1}{3}y + 6 - \frac{4}{3}y$

Step2: Combine constant terms

$-9 + 6 = -3$

Step3: Combine like variable terms

$-\frac{1}{3}y - \frac{4}{3}y = \frac{-1-4}{3}y = -\frac{5}{3}y$

Step4: Combine results

$-3 - \frac{5}{3}y$

Answer:

$-\frac{5}{3}y - 3$
