D. 9y+3
thank you
You're welcome.
To simplify the given expression, we need to combine like terms. Like terms are terms that have the same variable and exponent.
Given expression: 3y + 8y - 4 + 7 - 2y
First, let's combine the like terms involving y:
3y + 8y - 2y = 9y
Now, let's combine the constant terms:
-4 + 7 = 3
Putting it all together, the simplified form of the expression is 9y + 3.
Therefore, the correct answer is D. 9y + 3.
