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 let OX = a + λb be the vector equation of a line l1 and let OX = 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 and l2 in terms of a and b.
