no unique solution
the solution is line x+5y = 10
this is because one equation is multiple of another

x + 5y = 10
-2x-10y=-20 Add the two equations together
-x - 5y = -10 or x + 5y = 10 both equations are correct. I just multiplied every term in the first equation by -1

Though there are two variables x and y, and though there are apparently two equations, in reality, the second equation is the first equation multiplied by -2 and hence is not a real equation, which helps solving. So, the equation is effectively only one, x+5y = 10 and there is no unique solution.

eq.1 = -.5 of eq.2
there is no unique solution because the slope of the line of both equations is the same, and they will run overtop of one another forever.
