Answer: D and E
Step-by-step explanation:
To find this answer we want to get x by itself in the equation.
6x + 4 < 22
6x < 18
x < 3
So according to this the value of x has to be less than 3.
You can check your answer by substituting the values in for x.
6(0) + 4 < 22
4 < 22 is True
6(2) + 4 < 22
16 < 22 is True
6(3) + 4 < 22
22 < 22 False!
