What is the solution to the system? x + 3y - z = 6 4x - 2y + 2z = -10 6x + z = -12 a) (-4, 0, 12) b) (0, -2, -12) c) (-3, 5, 6) d) (2, 1, -3)

You have to substitute each value of the answer choices in order to pull the true statements. A helpful tool would be using this calculator to check the accuracy of the solution: https://www.mathpapa.com/algebra-calculator.html

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%
