Okay now there is more. There is brackets.
3[3(x+1)+2(x-1)]
Is this the answer?
[9x+9+6x-6]
No, that is not the correct answer. To simplify the expression with brackets, you need to apply the distributive property and combine like terms.
Here's the step-by-step explanation:
1. Start with the original expression: 3[3(x+1)+2(x-1)].
2. Distribute the 3 to both terms inside the first set of brackets: 3 * 3(x+1) = 9(x+1).
The expression becomes: 9(x+1) + 2(x-1).
3. Distribute the 2 to both terms inside the second set of brackets: 2 * (x-1) = 2x - 2.
The expression becomes: 9(x+1) + 2x - 2.
4. Multiply the terms inside the first set of brackets: 9(x+1) = 9x + 9.
The expression becomes: 9x + 9 + 2x - 2.
5. Combine like terms: 9x + 2x = 11x. And 9 - 2 = 7.
The final simplified expression is: 11x + 7.
So, the correct answer is 11x + 7, not [9x+9+6x-6].
