Answer 2

Step 1. Simplify brackets
-1/2 + 5/9
Step 2. Find the Least Common Denominator (LCD) of 1/2, 5/9
LCD = 18
Step 3. Make the denominators the same as the LCD
-1*9/2*9 + 5*2/9*2
Step 4. Simplify. Denominators are the same now.
-9/18 + 10/18
Step 5. Join the denominators
-9 + 10/18
Step 6. Simplify
Answer = 1/18
