1. The problem statement, all variables and given/known data Four 3-vectors a, b, c, and d are related by the equation ax + by + cz = d; where x, y, and z are real parameters. Using a suitable combination of scalar and vector products, find x, y, and z in terms of the vectors. 2. Relevant equations 3. The attempt at a solution I can solve the equations in component form, but have no idea how to solve in terms of scalar and vector products only.
