    5x - 20y = 10
    x is 6    y is 1
    5*6  - 20*1 = 10


    30 - 20 = 10


    I'm not sure how to show you the steps.  It is just obvious to me.   (It usually isn't.  Believe me.)

    5x-20y=10


    Step 1. Add 20y to both sides.


    5x  -  20y  +  20y   =  20y  +  10


    5x  =  20y  +  10


    Step 2. Divide by 5 on both sides.


    5x/5  =  20y/5  +  10/5


    Answer:


    x  =  4y  +  2


    Check:


    5(4y  +  2)  -  20y  =  10


    20y  +  10  -  20y  =  10  >  the 20y's cancels out.


    10  =  10
