This is the last of questions I have for my practice assignment. Again I will put what I got. Thanks for your help.
1.) Solve the system using substitution. Write answer as an ordered pair.
A.) First equation (-2,8)
B.) Second equation (-2,8)
I put A
2.) Solve the system using elimination. If the system is linearly dependent, state the general solution in terms of a parameter.
C.) (2z-3, 5z-7, z)
D.) no solution, inconsistent
I got D.
3. Solve using the method of your choice.
B) (-4, 2^8)
C) (4, 2^24) (-4, 2^8)
D) (4, 2^24) (-4, -2^8)
I got B
1. From substitution we get 4-2x= -5x-2
So, 3x = -6, x=-2, so y = 8: (-2,8)
2. Should be D
