A. Decide if the ordered pair is/is not a solution to the system. 1. (2,6); (3x - 2y = -4 (5x + y = 15 2. (4,-3); (3x - 4y = 24 (y=-x+3 B. Describe each system without graphing. State the number of solutions 1. (2x-3y = 5 (3y=2x-7 6x + 3 2. {2x=y=-11 3. S 6x + y = 3 (2x - y =-11 C. Determine the solution set of the given systems of equations. 1. (4x - 2y = 8 (2x = y + 4 { y = - ²/x +3 2. (3x - 4y = 24 3. 3x + y = 7 - 3x + 9

determine whether each ordered triple is a solution of the system of equations. y + z = -1 - 3z = - 19 25 6х (a) (2, 0, – 2) 1. 4x (b) (-3, 0, 5) 2y + 5z = 3x + 4y – z = (a) (3, – 1, 2) 17 2. {5x y + 2z = -2 2х - Зу + 7z (b) (1, 3, – 2) -21

HW 8 + 2 1. Solve the system. Show a a-2b-5c = -3 3a + b2c = -1 2a +3b+c= 4

I am stuck on this question. I have found z which equals -5 but have been unable to find x or y.
