Solve the system of equations.
-x + 2y + z + 6w = 2 x + y + 2z + w = 2
X + y + z + 2w = -1
A) (w - 7, -4w + 3, w + 3, w)
B) (w - 7, -4w + 3, -w + 3, w)
C) No solution
D) (-7w + 7, 4w + 3, w + 3, w)

Question

Quizplus · Accepted Answer

The system of equations can be solved by expressing the variables in terms of a parameter, w. Substituting and simplifying the equations leads to the solution (w - 7, -4w + 3, w + 3, w).
