If `x[(-3),(-4)]+y[(4),(3)] = [(10),(11)]`, then

If {:[(x-2y,2x-y),(3,4)]:}={:[(3,4),(3,4)]:} then find x and y.

Solve for x and y, when [{:(3,-4),(1," "2):}][{:(x),(y):}]=[{:(3),(11):}].

Find the value of x and y that satisfy the equations [(3,-2),(3,0),(2,4)] [(y,y),(x,x)]=[(3,3),(3y,3y),(10,10)]

If ({:(11, -4), (8, -3):})({:(-x, 4), (-8, y):}) = -({:(2, 3),(6, 9):}) , then find 2x - y.

If (1)/(x) + ( 2)/(y) = 4 and ( 3)/(y) - (1)/(x) = 11 then

If 4x+5y=83 and (3x)/(2y)=(21)/(22), then y-x=?( a) 3( b) 4 (c) 7 (d) 11

(4/3)^(-11)xx(3/4)^(-11)
