Question

An equation is shown below: 2(7x − 3) = 9 Which of the following correctly shows the beginning steps to solve this equation? (4 points)​

Answer 1

Hey there!

Use the distributive property and distribute 2:

2(7x-3)=9

14x-6=9

Now, add 6 to both sides (remember the golden rule of algebra)

14x=15

divide both sides by 14

x=15/14 (improper fraction)

x=1+1/14 (mixed number)

Hope everything is clear.

Let me know if you have any questions!

Answer 2

The next step is: 14x - 6 = 9. The answer to this equation would be: x = 15/14.

Explanation:

To solve this equation first you expand:

14x - 6 = 9

Then solve from there:

14x = 15

x = 15/14
