Um firstly, get one common variable at the top, so you would for example substract that 2x from 2x-y=1 and than you would have -y=-2x, divide that negative so you get y=2x. Substitute that y with 4y from 8x+4y=6, so it becomes 8x+4(2x)=6. Your answer was incorrect, I hope you can go from there or do you need further steps?
