Hi,

Understanding "to get a by itself" in order to "solve" for a is great!

We get a by itself on one side of the equation by performing allowable

operations (addition, subtraction, multiplication or division) on both

sides of the equation.

 x-4y = 8  

 x-8 = 4y       |adding 4y and subtracting 8 from BOTH sides of the EQ

 (x-8)/4 = y    |dividing both sides of the EQ by 4

 x/4 - 2 = y



3y-2x = 0

  3y = 2x

  y = (2/3)x
