3(X+y)=y if (X,y) is a solution to the equation above and y is not equal to 0 what is the ratio x/y ? I don't understand this question and would...

Hello!

It is not hard. As you know, usually to find two unknowns two equations are required. There are only one equation, so probably we cannot find and separately. But the question is not about finding and but only.

First, open the parentheses using the distributive law:

Then, move all terms with to the left and all with to the right (actually, add to both sides):

( by the distributive law also).

Now divide both sides of   by and then by and obtain

This is the ratio in question, -2/3.
