an equation is shown below:

2(7x − 3) = 9

which of the following correctly shows the beginning steps to solve this equation?

step 1:
14x − 3 =
9
step 2:
14x =
12

step 1:
14x − 6 =
9
step 2:
14x =
15

step 1:
9x − 3 =
9
step 2:
9x =
12

step 1:
7x − 1 =
9
step 2:
7x =
10

B. Step 1.  14x - 6 = 9
Step 2.  14x = 15

2(7x − 3) = 9

First step you would do is distribute your 2 to your 7x and -3.
You would get: 14x-6=9
Second step: You would add 6 to both sides because you would want to get your 14 x to where then you'll be able to get x alone.
You would get: 14x=15 < That would be your answer
B

Now if you want to continue to solve: 

Then you would divide each side by 14, because you'll want your x to be alone.
You would get: x=1.07

HOPE THIS HELPS! ^_^
