We'll break up this problem into two parts:
-(1/3)(-6y) = 2y, and (3x)(-3)(-1) = 9x
The overall answer is the product of these two: 9x*2y, or 18xy.
Multiply. Note that -(1/3) = -1/3
(-1/3)(-6y) = (6/3)y = 2y
(3x)(-3) = -9x
(2y)(-9x)(-1) = -18xy(-1)
Multiply
-18xy(-1) = 18xy
18xy is your answer
hope this helps
