2x - 6 = 4x + 6
First, you will want to eliminate all the variables on one side of the equation.
2x - 6 = 4x + 6
-4x -4x
-2x - 6 = 6
Then, you want to get rid of the constant on the side with the variable
-2x -6 = 6
+6 +6
-2x = 12
Now, subtract the coefficient from the variable
-2x = 12
/-2 /-2
x = -6
You now have your answer, which is x = -6.
When you perform an operation on one side, you must perform it on the other to make the equation even.
