Question 864076: (Hopefully I picked the right category!)
Given the system of equations:
2x – y = –2
x = 14 + 2y
What is the value of the system determinant?
What is the value of the y−determinant?
What is the value of the x−determinant?
What is the solution to the system of equations?

Hi
2x- y = -2
x - 2y = 14
x = 18/-3 = -6, y = 30/-3 = -10
D+=matrix%282%2C2%2C2%2C-1%2C1%2C-2%29 = -3
D%5By%5D+=matrix%282%2C2%2C2%2C-2%2C1%2C14%29 = 30
D%5Bx%5D+=matrix%282%2C2%2C-2%2C-1%2C14%2C-2%29 = 18
