Answer:

-3.

Explanation:

1. Write the expression.


(-9*2-(-3-6))/(1-(-2+1)-(-3))

2. Solve all parentheses.

We must change the symbol of all numbers that are inside a parenthesis, whenever the parenthesis has a "-" symbol before it.


(-9*2-3+6)/(1+2-1+3)

3. Simplify.


(-18-3+6)/(1+2-1+3)=\\ \\(-15)/(5)=\\ \\ -3.
