Question

Solve the system of equations.
4x + 3y + 8z − 5w = 1
2y+3z+w =−2
4x + y + 2z = 4
−x+5y +8w =−3

Answer 1

I would use matrices.

Answer 2

Make a coefficient matrix and a constant matrix. Then take the inverse of the coefficient matrix and times it by the constant matrix. The resulating matrix will be the solution to each letter in the order you listed them

Answer 3

Thank you!
