Answer:
There are infinitely many, but here are four
1. 22y
2. 66y/2 - 11y
3. 33y - 22y/2
4. -11y + 33y
Explanation:
1. Simplify the expression and you get 22y, so 22y is equivalent to 33y - 11y
2. 66y/2 equals 33y, so this expression is equivalent
3. 22y/2 equals 11y, so this expression is equivalent
4. This just flips the order, keeping the negative sign.
A - B can be written as A + (-B), which can be rewritten as -B + A
