Question

(2 points) Fill in the blanks with the correct coefficients when simplifying the expression. (18x+9y)+(2x+6y) %C2%A0x+ y

Answer 1

To simplify the expression \((18x + 9y) + (2x + 6y)\), we first combine like terms.

1. Combine the \(x\) terms:
- \(18x + 2x = 20x\)

2. Combine the \(y\) terms:
- \(9y + 6y = 15y\)

Putting it all together, we get:
\[
20x + 15y
\]

So, when simplified, the expression is \(20x + 15y\).

Thus, the coefficients are:
- For \(x\), the coefficient is **20**.
- For \(y\), the coefficient is **15**.

Final answer:
\[
20x + 15y
\]
