What is the sum of

(6x-27) = (3x+15)

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

3

(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
