`x+y=6` , If `y=3` then find `x`.

If x : y = 5 : 6 and y : z = 3 : 7 , then find x : z.

If 3x - 2y = 12 and 6x + y = 9 , then find the values of x and y

If x+y=[[5,2],[0,9]] and x-y=[[3,6],[0,-1]] , then find x&y .

If 6^(x-y)=36 and 3^(x+y)=729 , then find x^(2)-y^(2) .

if (x-y)^3=216 and (x-y)^5=32 , then find x^3-y^3 . The following steps are involved in solving the above problem. Arrange them in sequential order. (A) Therefore, x-y=6 and x+y=2 . (B) Solving x-y=6 and x+y=2rArrx=4, y=-2 . (C) x^3-y^3=64-(-2)^3=64+8=72 (D) (x-y)^3=216rArr(x-y)^3=6^3rArr x-y=6 and (x+y)^5=32rArr (x+y)^5=2^5rArr x+y=2 .

If x : y = 3 : 4 and y : z = 6 : 11," then find " x : y : z .

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

x is inversely proportional to square of y, when x = 4, then y = 3 . Find x , if y=6
