well, the answer did not display as intended.
first step, add (3/5) to each side, that cancels the (3/5) on the "x" side of the equation. second, multiply each side by y. This cancels the y on the left side and adds a *y on the other side. Third multiply each side by x. This moves the "x" to the other side and cancels it on the "y" side. Finally, divide each side by 2 so that "y" stands alone. that give you the final equation of: y=3x/10.
Always remember the rule: What you do to one side of the equation, you do to the other side of the equation. Hope this helps!
