For every black car sold at the Finest Car Sales, 4 red ones are sold. A total of 30 red cars and black cars were sold last month. How many cars of each color were sold?

It would be 7 black cars and 30 red cars

9 x 8 divided by (5-3)=36

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
