Question

Solve graphically each of the following systems of linear equations. Also, find the coordinates of the points where the lines meet the axis of x in each system:

(i) 2x + y = 6

x - 2y = -2

(ii) 2x - y = 2

4x - y = 8

(iii) x + 2y = 5

2x - 3y = -4

(iv) 2x + 3y = 8

x - 2y = -3

Answer 1

(i) x = 2, y= 2, (3,0) (-2,0)

(ii) x = 3, y = 4, (1, 0) (2,0)

(iii) x = 1, y = 2, (5, 0) (-2, 0)

(iv) x = 1, y = 2, (4, 0) (-3, 0)
