The lines 2x + y = 5 and x +2y=4 intersect at the point – InterviewSolution

1.

The lines 2x + y = 5 and x +2y=4 intersect at the point

Answer»

Point of intersection is2x + y = 5 ......(1)x + 2y = 4 ........(2)

eq(1) - 2×eq(2)2x + y = 5-2x - 4y = -8

-3y = -3y = 1So, 2x = 5-12x = 4x = 4/2x = 2

point of intersection is (2,1)
