A. 4x +3y = 20

  ----------------------------------------------------
(Coefficient of x)2+(Coefficient of y)2
     ---------------
= √(4)2+(3)2
    ---------
=
√16+9
    ------
=√25
=5

Now dividing both sides of the equation (i) by 5, we get
(4/5)x+(3/5)y=20/5

Which is the normal form of the given equation 4x + 3y  = 20.
