Simplify the expression by combining like terms.

Question

7x-3+2x+6

A
5x + 9

B
9x - 3

C
9x + 3

D
12x

Answer 1

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

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

2. Combine the constant terms: \[ -3 + 6 = 3 \]

Now, put it all together: \[ 9x + 3 \]

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

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