Andrew uses the equation 25(x-4)=30 x, where x represents the number of sales, to determine the number of items he needs to sell
pshichka [43]

Hello,

Start off by distributing 25 to both x and -4

25 * X = 25x & 25 * -4 = -100

25x - 100 = 30

At this point, we add 100 to both sides so we can get 25 to be seperate from 100.

25x = 130

To get rid of the 25, divide it in both sides:

130/25 = 5.2

The answer would be 5.2

I hope this helps you with your assignment!
