If `x:y=2:3` and `y:z=4:7` then find `x:z`.

If x:y=2:3 , y:z=3:4 , z:k=1:2 , find the value of x:y:z:k

If (x + y)/2 = (y+z)/3 = (z + x)/4 , then find x : y: z .

If x=2,y=-4 and z=1. FInd the value of 3x-7y^(2)+3xyz

If 2x = 3y = 4z, find x:y: z.

Find the values of x, y and z from the following equations: (i) [4 3x5]=[y z1 5] (ii) [x+y3 5+z x y]=[6 2 5 8] (iii) [x+y+z x+z y+z]=[9 5 7]

If X:Y=3:4,Y:Z=5:2 then find the value of X:Y:Z.

If A=[(x,y,z),(y,z,x),(z,x,y)] and A^3=I_3 and xyz=2 and x+y+z gt 0 find the value of x^3+y^3+z^3 is
