The graphical method isn't often used to solve any set of linear equations because it takes a long time, but take a look at it.

$x+y=1$ put any 2 distinct values of x to get 2 distinct values of y .

like the set of values could be

$x=1y=0$

$x=0y=1$

do the same for other equation . plot these values on graph .since these are linear equations the graph would show a straight line .

the point at which the lines intersect is common solution .

$x+y=1$ put any 2 distinct values of x to get 2 distinct values of y .
