Answer:
y = - 4
Step-by-step explanation:
x = - 2
3x - 2y = 2
substitute x = - 2 into 3x - 2y = 2
3(- 2) - 2y = 2 ← step 1
- 6 - 2y = 2 ( add 6 to both sides ) ← step 2
- 2y = 8 ( divide both sides by - 2 )
y = - 4
Answer:
Adding a negative number is the same thing as subtracting. a and -a are a zero pair so they cancel each other out. They are both the same distance from 0.

Your work is correct! Sally can only half 15 boxes per drive. She has 50 boxes. So, it takes her 3 drives to get 45 boxes to shops. Because she has to deliver 5 more boxes, Sally has to take one more trip. Sally has to take 4 total trips.
