Question

8x + 3y + 6 - 5x + 9y + 4

A. 25x + 10
B. 13x + 12y + 10
C. 3x + 12y + 10
D. 15xy + 10

Answer 1

Let's simplify the expression step-by-step:

1. Combine the \(x\) terms: \(8x - 5x = 3x\)
2. Combine the \(y\) terms: \(3y + 9y = 12y\)
3. Combine the constant terms: \(6 + 4 = 10\)

Putting it all together, we get:

\[
3x + 12y + 10
\]

So, the correct answer is:

**C. 3x + 12y + 10**
