i made this visualization about variable, is this okay?

i made this visualization so that my juniors wouldn't get confused, here's how it's work

• if the both side of the balance scale are equal, that's mean it's a equation (=)

• but if the both side of the balance scale are not equal, that's mean it's inequality (>, <, ≠)

• the block at the plate, it's represent for positive number

• but the block that look like a balloon, it's represent for negative number

is this really good for visualization? any recommendations?
