1. A room contains one-hundred people. Each person has hair that is either black, blonde, brown or red in colour. There are as many people with black hair as there are people with blonde, brown or red hair. Write down a linear system of two equations in four unknowns that encodes this information, and also write down the corresponding augmented matrix. So, the equations I got were: 25b+25l+25r+25d=100 b+l+r+d=100 is that correct? I am not sure.
