You reflect point A over the x-axis, double the distance from point a to the x-axis, then give the coordinates.
ex/ point A to the x-axis: 6, reflection: 12. coordinates (-6, 5)
2x-y =3
multiply by 4
8x - 4y = 12
3x +4y = 10 (unchanged equation)
------------------add
11x = 22
answer is A. the first.
first equation multiplied by 4 then sum to get 11x = 22
If you just think of a line graph you could do this on the y axis go up 6 and on the x axis go left 8 and make a right triangle with the 2 points you made and the origin and then use your equation to solve for the missing side
