Question

Solve the simultaneous equation X+y=4 and 2x-y=5 graphically​

Answer 1

Answer:

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

Answer 2

Answer:

(1) x + y=4

   (0,4)(4,0)

(2) 2x - y=5

    (0,-5)(3,1)
