How do you solve the system of equations by graphing #x-y=2, 2x=2y+10#?

There is no solution.
Explanation:
We have two simultaneous equations:
# { (x-y = 2, ......[A]), (2x=2y +10, ......[B]) :} #
Dividing equation [B] by
# { (x-y = 2, ......[A]), (x-y =5, ......[C]) :} #
And we see the equations are inconsistent, which we can validate graphically:
graph{(x-y - 2)(2x-2y -10)=0 [-10, 10, -5, 5]}
