To determine which set of numbers contains all the solutions of the inequality \(4x + 7 \neq 23\), we first need to find the value of \(x\) that makes the equation \(4x + 7 = 23\).
Starting with the equation:
\[ 4x + 7 = 23 \]
Subtract 7 from both sides:
\[ 4x = 16 \]
Now, divide both sides by 4:
\[ x = 4 \]
Thus, the inequality \(4x + 7 \neq 23\) means \(x\) can take any value except \(4\).
Now, let's evaluate the provided sets of numbers to find which set excludes 4:
- Set 1: \(1, 2, 3, 4\) - This set includes 4.
- Set 2: \(4, 5, 6, 7\) - This set includes 4.
- Set 3: \(2, 3, 5, 6\) - This set does not include 4.
- Set 4: \(3, 4, 6, 7\) - This set includes 4.
Only Set 3: \(2, 3, 5, 6\) contains numbers that are all solutions to \(4x + 7 \neq 23\).
