The answer is w - 2 = 4.
Step-by-step explanation:
w + 7= 11 is not correct because 4 + 7= 11 and the solution is true.
w - 1= 3 is not correct because 4 - 1= 3 and the solution is true.
6 + w = 10 is not correct because 6 + 4 = 10 and the solution is true.
w - 2 = 4 is correct because 4 - 2 does not = 4, but 2 and the solution is not true.
Therefore, w - 2 = 4 is correct.
I hope this Helps! Have a great day (:
