4x + y + 3/2z = 22
1/2x + 3z = 9
x + 5y = -19

wrote the equations just how it is written on my paper.

please help!

Answer 1

You have to solve it using a matric, isn't it ?

Answer 2

i think its elimination or substitution

Answer 3

Verify that {x = 6, y = -5, z = 2}

Answer 4

thanks for the answer but I also need the steps so I can fully understand how you got those answers
