To simplify the expression (2x + 2) - (3x + 11), we can distribute the negative sign to both terms inside the parentheses:
2x + 2 - 3x - 11
Next, we can combine like terms by subtracting 3x from 2x and -11 from 2:
2x - 3x + 2 - 11
This simplifies to:
-x - 9
Therefore, the simplified expression is -x - 9.
To simplify the expression 6(3x-5) + 2(3x-5) - 8(3x-5), we can distribute the coefficients to the terms inside the parentheses:
6 * 3x - 6 * 5 + 2 * 3x - 2 * 5 - 8 * 3x + 8 * 5
This simplifies to:
18x - 30 + 6x - 10 - 24x + 40
Next, we can combine like terms by adding the coefficients of the x terms and the constant terms:
(18x + 6x - 24x) + (-30 - 10 + 40)
This simplifies to:
0x + 0
Finally, any term multiplied by 0x is 0, and any constant added to 0 is the constant itself. Therefore, the simplified expression is:
0.
