Answer 1

From the set {15, 19, 23}, use substitution to determine which value of x makes the inequality true.

x - 4 < 7

23
none of these
15
19

Answer 2

The idea is to replace x with each number in the set one at a time.

So replace x with 15 to get

x - 4 < 7

15 - 4 < 7

11 < 7 ... which is FALSE, so x = 15 does NOT make x - 4 < 7 true

Answer 3

What happens when x = 19?
