Find `|x-y|` and `|y-x|` when `x=9` and `y=1/5`.

Find y when 3x+10y=5 and x=2

Find x and y when x+y=5 and 2x-3y=4

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

x varies directly with y and inversely with z. When y =5, z= 9 then x= 1/6 . Find the relation among three variables x,y and z and find the value of x when y = 6 and z = 1/5 .
