Step-by-step explanation:
To know if a = 3 satisfy the inequality, we need to replace a by 3 as:
7 + a < 11
7 + 3 < 11
10 < 11
Since 10 is less than 11, we can say that a = 3 satisfies the inequality.
In the same way, for a = 4, we get:
7 + a < 11
7 + 4 < 11
11 < 11
Since 11 is equal to 11, we can say that a = 3 doesn't satisfy the inequality.
For a = 5, we get:
7 + a < 11
7 + 5 < 11
12 < 11
Since 12 is greater than 11, we
