Final answer:
To simplify the expression, combine like terms step by step. The simplified expression is 4x - 4y.
Step-by-step explanation:
To simplify the expression, we need to combine like terms. Like terms have the same variables raised to the same powers. Let's simplify step by step:
- Combine the x terms by subtracting 3x from 5x to get 2x.
- Combine the y terms by subtracting 4y from 0 to get -4y.
- Simplify the fraction by multiplying 1/3 by (6x - 12y) to get 2x - 4y.
- Combine the x terms by adding 2x to the expression to get 4x - 4y.
- The simplified expression is 4x - 4y.
