-2y + 2
Explanation
We have (x - y + 1) - (x + y - 1)
Let’s expand the Parentheses
= x - y + 1 - x - y + 1
Then let’s group the like terms
= (x - x) + (- y - y) + (1 + 1)
= 0 - 2y + 2
= 2y + 2

5*9=45
**for my visual learners** in the parenthesis are groups of 5 sticks
( ///// ) **those are your apple slices** **now just do that exactly 9 times**
( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// )
5 10 15 20 25 30 35 40 45
