Answer: 14
Step-by-step explanation: Step 1: Subtract 3x from both sides.
6x-27-3x=3x+15-3x
3x-27=15
Step 2: Add 27 to both sides.
3x-27+27=15+27
3x=42
Step 3: Divide both sides by 3.
3x
3
=
42

(6x-27) = (3x+15)
You have to isolate the variable so in anyway possible you have to get all number to one side and the variable and their coefficient to the other side.
3x/3x and 6x/6x leaves you with (2x-27) = (15)
Next you can add 27 to each side to get rid of the 27 with 2x leaving the problem at
2x=42
Then divide by two
42 divided by 2 is 21
So x=21
