Answer:

[tex]\boxed{\large \{3, 4\}}[/tex]

Step-by-step explanation:

1. Solve the inequality

[tex]\begin{array}{rcll}7x + 6 & > & 20 & \\7x & > & 14 & \text{Subtracted 6 from each side}\\x & > & 2 & \text{Divided each side by 7}\\\end{array}[/tex]

2. Write the solution set

[tex]\text{The solution set from $\{1, 2, 3, 4\}$ that satisfies the inequality is } \boxed{\large \mathbf{\{3, 4\}}}[/tex]

Note that {2} is not a member of the solution set because

7(2) + 6 ≯ 20
