Colas has three fewer than twice the number of songs downloaded as Sabrina does
so we could write the equation as 2x - 3 which interprets the above statement as a function of x
here variable x is the no. of songs downloaded by Sabrina
so we can say that the meaning of the expression 2x – 3 is that colas has downloaded three fewer than twice the no. of songs downloaded by sabrina. the equation interprets this thing.
