Find the point of intersection of the straight lines 3y+4x=7 and 4y + 3x = 7, by drawing their graphs and looking for the point where they meet.

For equation 3y + 4x = 7


For different values of x and y



For equation 4y + 3x = 7


For different values of x and y



Plotting for both equations in same graph,



From graph it is visible that intersection point is P (1,1).


→ NOTE: You can verify intersection point by substituting it in both equations, and it should satisfy both equations.
