Question 34615
*[invoke describe_linear_equation 1, -1, 2]
*[invoke describe_linear_equation 1, 1, 6]
So we can see that the point where the two lines defined by the linear equations in the problem intesect is (4,2)
We can check our answer from the above by:
*[invoke linear "x", "y", 1, -1, 2, 1, 1, 6]

We again get x=4 and y=2 so we know that our answer is correct.
Hope this helps,
