Question

Write a real world situation that can be represented by the expression x - 12 subtraction

Answer 1

Ed has $37 and decides that he wants to go out to lunch with his friend Barb. They go out to eat, and when it comes time to pay the bill they decide to split it. It will cost Ed $12 to pay his half. How much money will he have left after he pays his share?

Answer 2

Let's say that 12 pictures were stolen from an art gallery.

Let x = number of pictures originally in the art gallery

The expression x - 12 in this situation means

that we take away 12 from our variable.

So 12 pictures stolen from the art gallery represents the expression x - 12.
