3x - x = 10

First subtract the 1x from the 3x, 3x - 1x = 2x (remember x is the same thing as 1x) to get:

2x = 10

Now divide both sides of the equation by 2 (remember if you do the same thing to both sides of an equation, you haven't changed the value of that equation) to get:

2x / 2 = 10 / 2

which equals:

x = 5
