`If [[x+2,y+3],[9,2]]= [[5,3],[9,2]] value of (x+y)=`

Q. If 2[[x,9],[y,6]]+3[[1,-1],[0,2]]=[[9,15],[12,18]], then the values of (x+y) is (A) 3 (B) 9 (C) -1 (D) -2

Q. If 2[[x,9],[y,6]]+3[[1,-1],[0,2]]=[[9,15],[12,18]], then the values of (x+y) is (A) 3 (B) 9 (C) -1 (D) -2

If x-9=2y and x+3=5y , what is the value of x?

Find the value of x, If [[3x+y,-y],[2y-x,3]]=[[1,2],[-5,3]]

If x : y=2:3, find the value of (3x+2y):(2x+5y)dot

If 7x - 15y = 4x + y , find the value of x: y . Hence, use componendo and dividendo to find the values of : (i) (9x + 5y)/(9x - 5y) (iI) (3x^(2) + 2y^(2))/(3x^(2) - 2y^(2))

If 3x+2y=12 and x y=6 , find the value of 9x^2+4y^2

For f(x ,y)= 7x +9y , what is the value of f(x,y) when y =((5)/(x))^(2) and x=3 ?

3x-y=3 , find the value of x and y 9x-3y=9
