Answer:

1. nonsense

2. x = 1, y = 2, z = -1, w = -2

Explanation:

1. Matrices are added term by corresponding term. Consider the upper left term in each matrix. The equation says 4 + 3 = 8. This is nonsense, so we cannot figure what you expect to solve.

__

2. This resolves to 4 equations:

• 3y = 6 ⇒ y = 2
• 3z = -3 ⇒ z = -1
• 2y+4x = 8 ⇒ 4+4x = 8 ⇒ x = 1
• 2z = w ⇒ -2 = w

The solutions are ...

(w, x, y, z) = (-2, 1, 2, -1)
