18 x + 21 y

Answer 1

To simplify the expression \( 15x + 14y + 3x + 7y \), we need to combine like terms.

1. Combine the \( x \) terms:

   • \( 15x + 3x = 18x \)

2. Combine the \( y \) terms:

   • \( 14y + 7y = 21y \)

So, the simplified expression is: \[ 18x + 21y \]

The correct response is: 18 x + 21 y
