Answer:

Step-by-step explanation:

matrix multiplication says you take the [x y] vector sideways (as is here) and mutliply by each row. So your top row is

3·x + -1·y which equals 3x-y.

Since this is the top row of your solution,

3x - y = 8.

The bottom row is the same process.

1·x + 2·y = 5

x + 2y = 5
