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
9.5 = 6 is incorrect so not A.
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
10.5 = 6 is incorrect so not C
Lastly D
6(0.5) + 12 = 9
3 + 12 = 9
15 = 9 is incorrect so not D either.
