Step 1.  Determine the "constant of proprotionality" k.  We are given the y varies directly with x  or y=kx
We are further given that 10 = k6 or k=10/6
Step 2,  Determine x from the 2nd relationship or 14 = 10x/6      just solve for x.

anonymous · Answer

all you have to do really is find the other x, if it gives you 2 y varies, there's not much else to but cross multiply and divide, isn't there? giving you 10 x 14 = 140/6 = 23.33333 so forth.
