To solve the first equation, we first simplify each side of the equation:

3(x - 3) = x + 2(x + 5)
3x - 9 = x + 2x + 10

Now, we combine like terms on each side of the equation:

3x - 9 = 3x + 10

Next, we move the variables to one side of the equation and the constants to the other side:

3x - 3x = 10 + 9
0 = 19

Since the result is 0 = 19, this equation has no solutions.

Now, let's solve the second equation:

2(x + 7) = 9 - 2x
2x + 14 = 9 - 2x

Combine like terms:

2x + 14 = 9 - 2x

Move the variables to one side of the equation and the constants to the other side:

2x + 2x = 9 - 14
4x = -5

Divide by 4:

x = -5/4

Therefore, the solution to the second equation is x = -5/4, while the first equation has no solution.
