In the set 3, 4, 6, 7 all the numbers are solutions of 4x + 7 ≠ 23.
When we substitute each number into the equation, we get:
3: 4(3) + 7 = 12 + 7 = 19 ≠ 23
4: 4(4) + 7 = 16 + 7 = 23, which is not equal to 23
6: 4(6) + 7 = 24 + 7 = 31 ≠ 23
7: 4(7) + 7 = 28 + 7 = 35 ≠ 23
Therefore, only the set 1, 2, 5, 6 is a set where all numbers are not solutions of 4x + 7 ≠ 23.
