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

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

Solve, using cross - multiplication : 4x - 3y - 11 = 0 6x + 7y - 5 = 0

Solve: x+2y+z=7 , x+3z=11 , 2x-3y=1

4x -5y-11z=12,. x-3y+z=1 2x + 3y-7z = 2
