Please help I'm stuck on this question.

Solve for x, y, and z:

2x - y - 4z = -12

2x + y + z = 1

x + 2y + 4z = 10

(x , y, z) =

Solve for x:

x^2-5x+6=0

12. II Consider the system of linear equations: 2 = 1 - 3y + z = 3 - 5 - 26 Which of the following is true? a) This system has a unique solution b) This system has exactly two solutions c) 'This system has infinitely many solutions d) This system bas no solution e) This system has a unique solution and then also infinitely many solutions D none of the others

3. Given two sets of equations Set #1: ty-2z=0 2x+2y-42=0 and and Set #2fx+y-2z=3 Set #2: 2+2y-42=4 Determine how many solutions these 2 sets of equations have. A) infinitely many/no solution B) infinitely many/infinitely many C) no solution/no solution D) only one solution/no solution E) none of these

Please using laplace transform
