@pleasehelpineedhelp Would you like to show your work so somebody can figure out your mistake?

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?
