To simplify the expression 2x + 3(x - 2) - 3(x - 6), we need to follow the order of operations: parentheses, exponents, multiplication and division (from left to right), and finally addition and subtraction (from left to right).

First, distribute the 3 to the terms inside the first parentheses:
2x + 3x - 6 - 3(x - 6)

Next, distribute the -3 to the terms inside the second parentheses:
2x + 3x - 6 - 3x + 18

Simplifying further, combine like terms:
(2x + 3x - 3x) + (-6 + 18)

The terms 3x and -3x cancel each other out, leaving:
2x + (-6 + 18)

Continue simplifying:
2x + 12

The simplified expression is 2x + 12.
