2x − y = 6 4x − 2y = 12

This is a system of equations. To solve for x and y, I recommend using the elimination method. You can multiply the top equation by -2. Then, the system would be.... -4x+2y = 6 4x-2y = 12 Then, you add the equations together and find the values of x and y. If the result makes no sense, then there's no solution.
