Answer:
Ivory is not correct.
Step-by-step explanation:
Ivory is not correct because of the way the first equation is treated. Ivory thinks 2x+2 can be double of what x+1 is. However, x can be anything, even 0. If we replace x with 0 in 2x+2, that would leave 2x = 0, and adding 2 would equal 2. If we look at x+1, we can add 1 to x and would equal 2. So Ivory is not correct, there is many equations other than this one that can equal.
The product/quotient of like signs are always positive.
The product/quotient of unlike signs are always negative.
ie.
