Hi, I am new to the forum. I am having trouble with solving three simultaneous equations using Cramer's Rule. I have forgotten the method.

I know the way I used to do it was to take a column outside and label it Q P and R using the cover-up method. Not too sure were to go from there.

Any help would be greatly appreciated.

Here is the question:

Use Cramer's rule to solve the following,

3Y + Z + 2X = 10

X - Y + Z -4 = 0

4X + 8 = Y + 5Z
