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 = 1 y = 0
x = 0 y = 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 .
