You can put this solution on YOUR website!
2x-y=-2 --> 2x-y+2 = 0
x=14+2y --> x-2y-14 = 0
What is the value of the system determinant?
|2 -1|
|1 -2| --> -4 -(-1) = -3
What is the value of the x-determinant?
|-1 +2|
|-2-14| --> 14 -(-4) = 18
What is the value of the y-determinant?
|2 +2|
|1 -14| --> -28-2 = -30
What is the solutions to the system of equations?
x = 18/-3 = -6
y = 30/-3 = -10
