Hi!
As you can see in the figure, the point you are looking for is the intersection of two lines.
The intersection point is found solving this system of linear equations (the point must satisfy both equations):
You can solve it, for example, by the method of substitution:
Then plug x1 into equation 2, and solve for x2:
Then you use the value of x2 to get x1:
