[22.2x-y=5],[4x-2y=7]

Show that the following systems of linear equations are inconsistent: 2x-y=5,\ \ 4x-2y=7

Show that the following systems of linear equations are inconsistent: 2x-y=5,\ \ 4x-2y=7

Show that the following systems of equations are inconsistent: {:(2x-y=5),(4x-2y=7):}

3x-4y=-7,5x-2y=0

The figure formed by the lines 2x-5y+4=0, 5x+2y+7=0, 2x-5y+3=0, 5x+2y-6=0 is

If [(2x+y,4x),(5x-7,4x)]= [ (7,7y-13),(y ,x+6)] , then the value of x and y is :

If [2x+y,4x,5x-7 4x]=[7 7y-13 y x+6] , then the value of x+y is x=3 , y=1 (b) x=2 , y=3 (c) x=2 , y=4 (d) x=3 , y=3

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

Determine the value of x+y if [(2x+y,4x),(5x-7,4x)]=[(7,7y-13),(y,x+6)]
