[" A "A+1/9times01" in "6" el anflix "],[(2)/(x)+(3)/(y)=3" and "(3)/(x)+(6)/(y)=5]

(x)/(2) - ( y )/(9) = 6, ( x) /( 7) + ( y ) /(3) = 5 .

If A=({:(2,3,10),(4,-6,5),(6,9,-20):}) find A^(-1) . Using A^(-1) solve the system of equations. (2)/(x)+(3)/(y)+(10)/(z)=2,(4)/(x)-(6)/(y)+(5)/(z)=5,(6)/(x)+(9)/(y)+(20)/(z)=-4

x+(6)/(y)=6,3x-(8)/(y)=5 then y=………

If A=[{:(2,3,10),(4,-6,5),(6,9,-20):}] , find A^(-1) . Using A^(-1) , solve the system of equations : {:((2)/(x)+(3)/(y)+(10)/(z)=2),((4)/(x)-(6)/(y)+(5)/(z)=5),((6)/(x)+(9)/(y)-(20)/(z)=-4):}

(x-4)(x-3)=(x-6)(x-5) (y-9)(y-3)= (y-4)(y-3)

If (x+3)/(4)=5 and (y-2)/(3)=6 then x and y are:

(x^(3))/(9y^(2))times(27y)/(x^(5)) =____.

Find each of the following products: (i) (x - 4)(x - 4) (ii) (2x - 3y)(2x - 3y) (iii) ((3)/(4) x - (5)/(6) y) ((3)/(4)x - (5)/(6) y) (iv) (x - (3)/(x)) (x - (3)/(x)) (v) ((1)/(3) x^(2) - 9) ((1)/(3) x^(2) - 9) (vi) ((1)/(2) y^(2) - (1)/(3) y) ((1)/(2) y^(2) - (1)/(3) y)

Find matrices X and Y , if X+Y=[(5, 2),( 0, 9)] and X-Y=[(3, 6),( 0,-1)] .

Find x and y if :- x + y = [(5,2),(0,9)] and x-y [(3, 6),(0,-1)] .
