Question

Which of the following does not belong to the solution set of -3x + 7 < 11? 4 -1 -5 0

Answer 1

-5 Is not a solution to the inequality

Answer 2

-5

Explanation:

We can just see what x has to be smaller than (or plug in the numbers, but that is more time-consuming).

-3x + 7 < 11 -> -3x < 4 -> x > -4/3

-5 is the only number that is less than or equal to -4/3.
