Well it depends on what your teacher or your book says it is. You see yx and z are all letters called variables. Any letter can be a variable. The letter can equal any amount. It'll will be of course what your book or teacher says it'll be. Example: if y=3 then 7+y=3 y does not always have to be 3. it can be any number in the world. There is no permanent number for a variable. Example: if y=18 then y+2=20 You see a variable (which is any letter in the alphabet) can be equal to any number in the world.
