Answer:
1. nonsense
2. x = 1, y = 2, z = -1, w = -2
Step-by-step 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)
