3 × is partly constant and partly varies with y . when y =3, × =7 and when =6× =9× =14 . find the relationship between ×and y

Answer 1

x = a+by
and, using the points they gave,
a+3b = 7
and the rest is garbage.

How about you retype "when =6× =9× =14" so it makes sense, and for Pete's sake, use "x" for the variable! "×" is the multiplication operator. Why not use the very handy "x" key on your keyboard? You found "y" well enough.
