answer:
To simplify the expression (2x + 6) + (4x - 2), we need to combine like terms.
First, let's remove the parentheses by distributing the terms inside:
2x + 6 + 4x - 2
Next, we can combine the like terms. Like terms are terms that have the same variable and exponent.
Combining the x terms, we have:
2x + 4x = 6x
Combining the constant terms, we have:
6 + (-2) = 4
Therefore, simplifying the expression (2x + 6) + (4x - 2) gives us:
6x + 4
