In order to solve this equation, you must focus your efforts on isolating x. First, add 4x to both sides of the equation. This will eliminate it on the left and cause the equation to look like this: 35=15+4x. Next, you need to subtract 15 from both sides <span>which will eliminate it on the right and cause the equation to look like this: 20=4x. Finally, you must divide both sides of the equation by 4. Ta-da!~ This leaves you with x=5.
The answer is x=5.
Good luck and good day! c:
