[5x+3y=11],[2x-7y=-12]

Solve the following pair of linear equations by cross multiplication method : 2x+3y= 11/3 , 5x-7y=31/3 .

Solve the following system of equations: 2x-3y+5z=11, 5x+2y-7z=-12, -4x+3y+z=5

The line 5x-2y=11 and 2x+3y=12 intersect at :

1 + 5x + 3y = 9 2x 3y = 12 X = (x, y) - 4

Solve: x+y=11,2x-3y=7

If [[3,-2],[-1,2]][[x],[y]]=[[11],[-5]] then 3x+7y=
