    Divide both sides by 5 to isolate x.

  2. Divide both sides of the equation by 4 to get the answer.

    x = 4 . It has to be 4 if the equation is to be valid.

  3. 5x=20

    This means that 5 times some number is 20. To find that number, divide both sides of the equation by 5.

    5x = 20
    x = 20/5
    x = 4
