For which inequality would x = 2.7 not be a solution?

x + 14 < 9

x - 4 < 0

3x + 6 ≥ 10

6 - x ≥ 1

Best way to solve this is to substitute the value of x to all of the inequalities

x + 14 < 9

2.7 + 14 < 9

16.7 < 9 (False)

x - 4 < 0

2.7 - 4 < 0

-1.3 < 0 (True)

3 (2.7) + 6 ≥ 10

14.1 ≥ 10 (True)

6 - x ≥ 1

6 - 2.7 ≥ 1

3.3 ≥ 1 (True)
