Take the derivatives of each to get the tangent vectors:
Take the cross product of the tangent vectors to get a vector that is normal to both lines:
The two given lines intersect when :
that is, at the point (6, 4, 4).
The line perpendicular to both of the given lines through the origin is obtained by scaling the normal vector found earlier by ; translate this line by adding the vector to get the line we want,
There is only 1 whole 5/9's in the number 1.
So what you are saying is 1USD = 1EUR × 1.3847
Now to put this around
100EUR = X × 1.3847USD
