Simplify the expression shown.

3 х + 2-3 х + 7 + 5 х

What is the coefficient in the simplified expression?

A: 5

B: 9

C: 3x

D: 5x

Answer: A. 5

Step-by-step explanation:

First you simplify.

3x+2-3x+7+5x

3x and - 3x cancel each other out. In other words eliminate the opposites.

2+7+5x

Add like terms. 2+7=9.

The simplified expression is 5x+9.

A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e. g. 4 in 4x y).

So the coefficient for the simplified expression would be 5.
