Hello, I am doing an independent study on matrix operations and made a few problems up so someone can show me how to break them down and solve. I am really having a hard time understanding them and I figure that the best way to learn them would be from the work and each individual step. If someone has the time, please help me by breaking each of these four problems down for me, so I know how to do them. I appreciate anyone who is willing to help.

IMPORTANT: Each section of brackets, for example, as in question #1, is to be read as the first row [2 3] or second row [3 5] of one matrix. I had to ask because I wrote it according to some poorly written problems and didn't understand what it meant.

1. [2 3] [3 5]

2. [6 8] [5 7]

Find the matrix X:

3. [6 5] [4 -2] * X = [18 49] [-20 6]

4. [3 4] [-3 -2] * X = [10 -10] [-8 8]
