1. True
Explanation: (12+8) = 20 . . . 20/10 = 2 and 12/6 = 2
2. False
Explanation: 3(-6) = -18+5 = -13 . . . 26-3 = 23
3. I'm not quite sure about this one, but here's what I got:
Explanation: 8x-3 /8 = x=3/8 . . . 10x-1 /10 = x=-1/10
Also with the "open" option I've never heard of that option before so I'm not sure about that answer choice.
