Question: Use elimination/substitution to solve all problems 5x-2y + 3z = 20 4x-3y + 52 = 31 12. 2x-4y-32 = -9 14. -x + 2y +

Use elimination/substitution to solve all problems 5x-2y + 3z = 20 4x-3y + 52 = 31 12. 2x-4y-32 = -9 14. -x + 2y + 4z = 20 x + 6y-8z = 21 x + 5y-2z = -29 2x - y + 3z = 17 10x + 2y-14z = 8 17. -5x + 4y-22 = -46 22. -x-2y-42 =-1 2y + 5z = -7 -12x-6y + 62 = -12
