`2x-6y=3` put `x=-5`

2x-y=1 ; 6x+3y=5

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

Solve the following equations by inversion method. 2x+6y = 8 , x+3y = 5 .

Show that each of the following systems of linear equations is consistent and also find their solutions: 6x+4y=2 9x+6y=3 2x+3y=5 6x+9y=15 5x+3y+7z=4 3x+26 y+2z=9 7x+2y+10 z=5 x-y+z=3 2x+y-z=2 -x-2y+2z=1 x+y+z=6 x+2y+3z=14 x+4y+7z=30 2x+2y-2z=1 4x+4y-z=2 6x+6y+2z=3

I. 2x-3y=- 3.5 IIgt 3x-2y =- 6.5

If (3x -4y) : (2x -3y) = (5x -6y) : (4x -5y) , find : x : y .

2x+3y=2,5x-6y=0 then find the value of 'x'

2x+3y=5 6x+9y=10

2x+3y=8 4x-5y=-6
