The allowable operations that will maintain the equality are adding the same amount to each side of the equation and multiplying each side of the equation by the same amount. In my equation 3x  5y = 12 I don't want the 5y term on the left of the equality so I add 5y to each side to obtain
or
This is almost what I want, only the 3 on the left side is a problem. If I divide each side of the equation by 3 I get
or
which is
Now try your equation,
