Final answer:
The expression (3x - 5) + (3x + 6) simplifies to 6x + 1.
Step-by-step explanation:
To simplify the expression (3x - 5) + (3x + 6), we first need to combine like terms. Like terms are terms that have the same variable and exponent. In this case, we have 3x and 3x which are like terms, so we can add them together. We also have -5 and 6 which are constants, so we can add them together as well. Combining like terms, we get:
- 3x + 3x = 6x
- -5 + 6 = 1
Therefore, the simplified expression is 6x + 1.
