What is the simplest form of the expression \( (-11.7 y-3.3 x)+1.2 x+(5.2 y+x) \) ? \( -16.9 y-5.5 x \) \( -16.9 y-4.5 x \) \( -6.5 y-2.1 x \) \( -6.5 y-1.1 x \)

To simplify the expression \( (-11.7 y - 3.3 x) + 1.2 x + (5.2 y + x) \), we can combine like terms. Starting with the \( y \) terms: - Combine \( -11.7 y + 5.2 y = -6.5 y \). Next, for the \( x \) terms: - Combine \( -3.3 x + 1.2 x + x = -3.3 x + 1.2 x + 1.0 x = -1.1 x \). Putting it all together, the expression simplifies to: \[ -6.5 y - 1.1 x. \] So the correct answer is \( -6.5 y - 1.1 x \).
