Question: y = 2x - 2 3x - 6y = -6 How do I solve using the matrices? How do I find this? The difference of

y = 2x - 2

3x - 6y = -6 How do I solve using the matrices?

How do I find this? The difference of two numbers is 4. 5 times the smaller number is four more than three times the larger. What are the two numbers I am looking for?

The sum of three numbers is 12. The first number is the difference of the other two numbers. When you add the other two numbers and subtract 8, the result will be the first number.

x + y + z = -6

x - y + z = -2

2x + y - 3z = 5 Would it be possible to solve this without using matrices? I was taught to solve equations with 3 variable with matrices only but I don't want to do that.

How do I find the fourth term of (x + y)⁸?
