Question

Use matrices to solve the following sets of Simultaneous Linear Equations:

3x + y = 5

x + 3y + z = 10

5x + 2y – 3z = 0

Answer 1

How do I use matrices to do this??

Answer 2

you need to choose two variables and set them so they cancel each other out. Then do a similar process for two different ones so you can isolate the values for the different variables.

Answer 3

For example
3x + y = 5
x + 3y + z = 10

What would you need to multiply the second one by to cancel out 3x?

Answer 4
