Mario has read two less than four times the number of books tonya has read. what factored expression represents the number of books, x, mario has read?

Let X be the variable used to represent the expression of the total number of books that Mario has read.
We used 4X to represent "four times the number of books". Then we add -2 to interpret the words "for two less than".
Therefore, we have an expression of 4X-2 for the total number of books that Mario has read.
