Hi,
Solving the system of equations by the substitution method
   x + y = 5 Or y = -x + 5 Green line
  2x + y = 6 Blue line
  2x + (-x+5)) = 6
        x = 1
         x = 1   and y = 4   (-1+5)
Ordered pair (1,4) the solution for this system
{{{drawing(300,300,   -6, 6, -6, 6, grid(1),
circle(1, 4,0.3),
graph( 300, 300, -6, 6, -6, 6,0, -x + 5, -2x +6))}}}
