Starting with the first part of the inequality:

3x - 8 ≤ 23

Add 8 to both sides to isolate 3x:

3x ≤ 23 + 8

3x ≤ 31

Now, divide both sides by 3 to solve for x:

x ≤ 31 / 3

So, the first part of the inequality gives us:

x ≤ 31/3

Now, let's solve the second part of the inequality:

-4x + 26 ≥ 6

Subtract 26 from both sides:

-4x ≥ 6 - 26

-4x ≥ -20

Divide both sides by -4. Remember that when you divide or multiply an inequality by a negative number, you need to reverse the inequality sign:

x ≤ -20 / -4

x ≤ 5

So, the second part of the inequality gives us:

x ≤ 5

Now, combining both parts, we have:

x ≤ 31/3 OR x ≤ 5

The correct choice is (Choice C):

5 ≤ x ≤ 31/3
