Basically the first thing you're going to have to do is move the y's to one side of the equal sign. To do this you can either add 0.3y to both sides of the equation OR subtract 0.7y from both sides of the equation.

First, you would add 12 to both sides to get 30-0.3y=0.7y. Then you would add 0.3y to both sides to get y by itself. Y=30
