PLEASE HELP QUICK WORTH ALOT OF POINTS

Answer 1

-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.`
