I dont really even know where to start with this? Id be really greatful for some helpLet a and b be non-zero vectors which are not parallel to each other. Further letOX = a + λbbe the vector equation of a linel1and letOX = 2a + μ(a + b)be the vector equation of a line l2 (with λ,μ real numbers). Express the position vector of the intersection of the two lines l1 andl2in terms of a and b.
