Question

Which of the following is an open statement?

3 + 10 = 13
2x + 5x = 7x
14 ÷ 2 = 7
3x = 12

Answer 1

3x = 12

Explanation:

Answer 2

I think the last one because a open statement contains at least one blank that becomes true or false when it’s filled in if you fill x with 4 you will get 3(4) 3*4=13 so if that blank was filled in with 4 it would be true
