Describe each step in solving equations with variables on both sides. do not just list the steps, but describe each.

Well lets start with an equation.

Let's say 3b=6a, in order to solve this you would first have to choose a variable and isolate it
 
 b=(6a)/3, With the new isolated variable you can now plug in.

3((6a)/3)=6a, By working this out you should have isolated the variable "a"

a=1, plug into the original equation and solve for the remaining variable

3b=6(1) -> 3b=6 -> b=6/3 -> b=2

hopes this helps

hope it is correct if not i'm srry i tried to
