To solve the equations, we will solve each equation separately.

  1. Solve the first equation: \(-3x + 7 = 10\)

    Subtract 7 from both sides: \(-3x = 10 - 7\) \(-3x = 3\)

    Now, divide both sides by -3: \(x = \frac{3}{-3}\) \(x = -1\)

  2. Solve the second equation: \(3x - 9 = 0\)

    Add 9 to both sides: \(3x = 9\)

    Now, divide both sides by 3: \(x = \frac{9}{3}\) \(x = 3\)

Now we combine the solutions from both equations: The solution set is \({-1, 3}\).

Thus, the correct response is: \({-1, 3}\)
