In order to find x-axis interception coordinates you need to set other two variables (y and z) to zero and solve the remaining equation.
So the following simple equations need to be solved:
2x = 40
5y = 40
-4z = 40
It intercepts x-axis at coordinates (20;0;0), y-axis at (0;8;0) and z-axis at (0;0;-10).
I thinks that the answer is 9
