To find the solution set for the inequalities \(4x - 3 > 9\) and \(x + 6 > -2\), we will solve each inequality separately.

  1. Solve the first inequality:
    \(4x - 3 > 9\)

    Add 3 to both sides:
    \(4x > 12\)

    Divide by 4:
    \(x > 3\)

  2. Solve the second inequality:
    \(x + 6 > -2\)

    Subtract 6 from both sides:
    \(x > -8\)

Now we have the two inequalities:

  • \(x > 3\)
  • \(x > -8\)

The more restrictive condition is \(x > 3\) since any number greater than 3 is also greater than -8. Thus, the solution set is:

\[ {x | x > 3} \]

Therefore, the correct response is:

A) {x | x > 3}
