Which expression means 5 less than the product of 9 and a number w

9 x w = x

x - 5= y

Step-by-step explanation:

9 x w = x                                  w = a variable that equals the second multiplier.

                                                x = a variable that equals the product of 9 and x.

x - 5 = y                                     y = a variable that  equals the end value.
