Let's call "a number" x. Then 5 more than twice x is 5 + 2x.
Well, isn't that just a happy little expression! To represent "three more than a number" in algebra, you would write it as "x + 3," where "x" represents the unknown number. Just like adding a touch of color to a painting, adding 3 to a number can bring a new dimension to your mathematical expressions.
