Answer:

B. 2x + 3 = 4

Step-by-step explanation:

6x + 9 = 12

Find this out by solving for x start with subtraction property of equality.

6x = 3

Division property of equality

x = 3/6 or x = 0.5

_____________________

Now insert the value of x to check other answers starting with A

0.5 + 9 = 6

<em>9.5 = 6 is incorrect so not A.</em>

Now B

2(0.5) + 3 = 4

1 + 3 = 4

4 = 4 is correct so B is your answer

Now C

3(0.5) + 9 = 6

1.5 + 9 = 6

<em>10.5 = 6 is incorrect so not C</em>

Lastly D

6(0.5) + 12 = 9

3 + 12 = 9

<em>15 = 9 is incorrect so not D either. </em>

Step-by-step explanation:

(6x + 9)/3 = 12/3

2x + 3 = 4 ---> which matches choice B
