Question

Is the equation True, False, or Open?
1. (12+8)÷-10=-12÷6
2. 3(-6)+5=26-3
3. 8x+3=10x-1

Answer 1

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.
