Question

x+y=5;2x-y=4 solve graphically

Answer 1

Given equations are

x+y = 5 ...(1)

And 2x-y = 4 ...(2)

For drawing equation (1) on graph, we have

x	5	0	3
y	0	5	2

For drawing equation (2) on graph, we have

x	2	0	3
y	0	-4	2

We observe from graph that intersection point of both lines is (3, 2).

∴ solution of given system of equation is x = 3 and y = 2.
