Jackie got (4, -2) as her solution to a linear system. She was checking the solution in the first equation, 2x - y = 6. She decided that (4, -2) did work in that equation, and she was getting ready to check the second equations. Her friend was doing the same problem and told Jackie she had made an error when doing the check. The friend is correct. What mistake did Jackie most likely make that would cause her to think (4, -2) was the solution? <3 Thank you

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
