Answer:
x = 30
Explanation:
First you would add the like terms, which are 2x and 4x, which gives you 6x. Now the equation would read 6x + 6 = 180
You need to get rid of the six, and since what you do to one side of the equation must be done to the other, you need to subtract 6 from both sides to cancel out the 6 on the left side of the equation. The equation is now 6x = 180. Now you need to divide both sides by 6, which gives you x = 30.
