y-1=4y-2/3

-4y        -4y        

-3y-1=-2/3

+1          +1

-3y=1-2/3

-3y=3/3-2/3

-3y=1/3      /:(-3)

y=1/3*(-1/3)

y=-1/9

y - 1  =  4y - 2/3.      Move the ys over to one side,  +4y crosses over to become -4y,
                                  and -1 crosses over the right side to become +1.
y -4y  = -2/3  + 1
-3y  =    1 - 2/3
-3y =  1/3          Divide both sides by -3.

-3y/-3  = (1/3) / -3.
y  =  1/3  * -1/3
y =  - 1/9
