The first equation is -3x + 7 = 10. Subtracting 7 from both sides of the equation gives -3x = 3. Dividing both sides by -3 gives x = -1.
The second equation is 3x - 9 = 0. Adding 9 to both sides of the equation gives 3x = 9. Dividing both sides by 3 gives x = 3.
Therefore, the solution set is x = {-1, 3}.
