Fill in the blanks with the correct coefficients when simplifying the expression.

Question

(18x+9y)+(2x+6y)

__ x+__ y

Answer 1

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

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

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

So, the simplified expression is: \[ 20x + 15y \]

Thus, the coefficients are: 20 for \(x\) and 15 for \(y\).

Final answer: 20 x + 15 y
