[" 68"x=],[[" 12."x+y,=14],[,x-y=4]]

x+y=14 and x-y=4

x + y = 14x-y = 4

x + y = 14x-y = 4

3x+2y=14; x+4y=7

If [[x-y,z],[2x-y,w]]=[[-1,4],[0,5]] then find the value of x+y.

If [[x-y,z],[2x-y,omega]] = [[-1,4], [0,5]], find x,y,z,w

4x+14y=50;6x-2y=6

x+3y = -4 ; 5x-7y=68

In Fig.70, if A B C D , then the value of x\ a n d\ y are x=24 ,\ y=48 (b) x=34 ,\ y=68 x=24 ,\ y=68 (d) x=34 ,\ y=48

Classify the following pairs of lines as coincident, parallel, perpendicular or intersecting : (i) 6x+14y-16=0 , 12x+28y-32=0 (ii) 3x-4y=8 , 3x+4y=11 (iii) 5x-2y=7 , 2y-5x=-7 (iv) 4x+7y=19 , 7x-4y=-2 (v) x-2y=7 , 4y-2x=13
