6) Given only the number of users in 2005 and the assumption that the number of users triples each year, how did you determine the number of users for years 0,-1, -2, and -3?
a. Divide the next year's number of users by 2.
b. Halve the next year's number of users.
C. Divide the next year's number of users by 3.
d. Subtract 3 from the next year's number of users.

x=-2

step-by-step explanation:

i began by flipping the problem to give me x= on the left (keeps it clearer for me).   so my problem simply became 10x-3=4x-6.  

1)   subtract 4x from the right side, which equals 0.   you do the same to the left of the equal as the right; therefore, subtract 4x from 10x, leaving 6x on the left.

              10x-3=4x-6   :   4x-4x on the right leaves only the -6        

2)             6x-3= 0-6 :    

                6x+3=   -6

3) divide
