To simplify the equation, we first distribute the negative sign and the parentheses:

2x + x - 3 - 23 - 2 + 3x = 0

Combine like terms:

3x + x + 3x - 3 - 23 - 2 = 0

7x - 28 = 0

Now, add 28 to both sides of the equation to isolate the variable x:

7x = 28

Divide by 7:

x = 4

Therefore, the solution to the equation 2x + (x-3) - 23 - (2 - 3x) = 0 is x = 4.
