I will mark you brainliest if you get all 4 answers right. I literally wasted 91 points for this question. I need help on 4 questions that'll be in the link. They are multiple choice so please help me. I am beyond desperate.

Answer:6. ○ [-6, 8]5. Fourth bubble3. ○ No Solution1. ○ [5, 0]; Value is 35Step-by-step explanation:6.{-8x - 8y = -16{6x - 9y = -108¾[-8x - 8y = -16]{-6x - 6y = -12 >> New Equation{6x - 9y = -108______________-15y = -120____ ____-15 -15y = 8 [Plug this back into both equations above to get the x-coordinate of -6]; -6 = x__________________________________________________________1. All you do is take each answer choice and plug it into each function to confirm their authenticities.__________________________________________________________5. From what I have seen about matrices, just write then side-by-side as you see it.__________________________________________________________3.{-3x - 4y - 3z = -7{2x - 6y + 2z = 3 ←{5x - 2y + 5z = 9 ←{2x - 6y + 2z = 3{5x - 2y + 5z = 9-⅓[2x - 6y + 2z = 3]{-⅔x + 2y - ⅔z = -1 >> New Equation{5x - 2y + 5z = 9____________________4⅓x + 4⅓z = 8 - 4⅓z -4⅓z_________________4⅓x = -4⅓z + 8____ _________ 4⅓ 4⅓x = -z + 1 11⁄135[-z + 1 11⁄13] - 2y + 5z = 9-5z + 93⁄13 - 2y + 5z = 99 = 9 3⁄13 - 2y-9 3⁄13 -9 3⁄13______________-3⁄13 = -2y____ ___ -2 -23⁄26 = y5[-z + 1 11⁄13] - 2[3⁄26] + 5z = 9-5z + 9 3⁄13 - 3⁄13 + 5z9 = 92[-z + 1 11⁄13] - 6[3⁄26] + 2z = 3-2z + 3 9⁄13 - 9⁄13 + 2z = 33 = 3* So you see, ever since we defined y and partially defined x, the z-terms keep canceling each other out, therefore indicating that we have NO SOLUTION.*** I apologize that I have not had the time to teach myself how to solve using matrices, which I have heard of, but was never taught it. I hope you can understand my entire explanation.I am delighted to assist you anytime.
