[" 5."x+y=6],[x-y=2]

5x-y=9; 6x-2y=10

6.If [[x+y,6],[5,2x-y]]=[[0,6],[5,3]] then the value of x+y is

4x-2y=3 6x-3y=5

Show that the following equations are consistent: 5x+6y=11,x+y=2,2x+3y=5

2x+3y=5 4x-5y=6

3x - y= 5, 6x - 2y = 10 .

If the equation lambda x^(2)-5 x y+6 y^(2)+x-3 y=0 represents a pair of lines, then their point of intersection is

Show that the following systems of linear equations are inconsistent: 3x+y=5,\ \ -6x-2y=9

Show that the following systems of linear equations are inconsistent: 3x+y=5,\ \ -6x-2y=9
