Whenever there's a denominator. Multiply all whole equation with the denominator. For example, the denominator here in the equation is 3. So we multiply the whole equation by 3.

Moving the x to the same term which goes for the same as the constant for easier in solving.

Moving to the another side, changing the sign/operator to opposite (From plus to minus, from multiply to divide.)

Move 2 to another side, aka to divide 18.

Therefore, the answer is x = 9.
