If `[x+y x-y]=[2 1 4 3][1-2]` , then write the value of `(x ,\ y)` .

If [x+yx-y]=[2143][1-2], then write the value of (x,y)

If (x+1,y-2)=(3,1) , write the values of x and y.

If [[3,x],[7,5]]+[[1,-2],[-4,y]]=[[3,2],[5,1]] then write the value of x and y.

If [[x,y]]+[[3,4]]=[[2,-1]] then what are the values of x and y?

If [(x,x-y),(2x+y,7)]=[(3,1),(8,7)] write the value of y.

If [{:(x-y," "2y),(2y+z,x+y):}]=[{:(1,4),(9,5):}] then write the value of (x+y+z) .

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

If ((2x-y)/(x+2y))=(1)/(2), then find the value of ((3x-y)/(3x+y))
