4x-x=2013

To solve the equation 4x - x = 2013, we can simplify the left side of the equation by combining like terms:

4x - x = 3x

So, the equation becomes:

3x = 2013

To solve for x, divide both sides of the equation by 3:

3x / 3 = 2013 / 3

x = 671

Therefore, the solution to the equation 4x - x = 2013 is x = 671.
