Answer:
x=4
Explanation:
3 ( 4x -7 ) = 27
First you will multiply: 3 times 4x and 3 times -7. This is called distrobution.
Now you have: 12x -21 = 27
You will need to add 21 to -21 and 27. You will do this because the positive will take away the negative, they cancel each other out.
What you have now should look like this: 12x = 48.
Now all you need to do is divide 48 by 12 (48/12) to get x=4.
