For solving the problem graphically, we need to plot the graph of both the equation .. where ever these two line intersect each other become solution of the equations
so 2x-4y = 10 we can write x = 5-2y
Now put y = 0, 1, 2 ... & get values of x = 5,3,1 .... (respectively)
Similarly for x + y = 2 we can write x = 2-y Now put y = 0, 1, 2 ... & get values of x = 2,1,0 .... (respectively)
plot these point
These lines intersect at ( 3,-1) Hence x = 3 & y = -1 (Answer)
Please don't forget to choose as best to regard my efforts !!!
