An algebraic expression is, obviously, an expression with a variable. "A number" would represent a variable, which, in this case, we'll use y. So, 15 decreased by twice x. 15 - y x 2 =  I hope this helped :)

15-2x= that would be the algebraic equation. Remember that decrease usually means minus. A number is always represented by a variable, and then anything that by is usually a multiplication or division depending on how its stated.
