Iwill give brainliest and all my points i have if someone can just give me the correct answers to the questions below. i really need to get all these questions right and these are the only two i can’t figure out. . what is the solution of the system of equations? {-3x - 4y - 3z = -7 {2x - 6y + 2z = 3 {5x - 2y + 5z = 9 a. (5,-2,7) b. (-5,2,7) c.(5,2,-7) d. no solution use a matrix to find the solution to the system of equations. {-8x - 8y = -16 {6x - 9y = -108 ,8) b.(6,8) c.(8,-6) d. (6,-8)
