Question

Solve the system of equations using Gaussian elimination or gauss-Jordan elimination.

Answer 1

5x+4y+z=3
4x-3y-z=37
5x+y+2z=16

Answer 2

Add equation 1 and 2 together, the z terms subtract out.
Multiply the second equation by 2 and add the result to the third equation, the z terms
will subtract out.
You now have two equations in two unknowns.
