1 answer

To simplify the expression \( 7x - 3 + 2x + 6 \), we can combine like terms.

  1. Combine the \( x \) terms: \( 7x + 2x = 9x \)

  2. Combine the constant terms: \( -3 + 6 = 3 \)

Putting it all together, we get: \[ 9x + 3 \]

Thus, the simplified expression is \( 9x + 3 \).

The correct answer is C \( 9x + 3 \).
