How to solv the foll graphically-

x-2y=0

3x+4y=20

PLS, ITS URGENT!!!!

the given equation of the straight line are 

the point (0, 0) and (2, 1) lies on the straight line (1).

plot the points and join them to get the line (1)

the point (0, 5) and (4, 2) lies on the straight line (2).

plot the points and join them to get the line (2).

the intersection point is (4, 2).

therefore x = 4 and y =2 is the solution of the given equations.

hope this helps you.

cheers!!
