You say this is a matrix question, so you're taking a course in linear algebra? If you want an explanation at how to get this answer, you might want to understand the concept of linear dependence, or better formulated linear independence. 

However, by focussing your eyes on the equations you should see that the second line of equations is three times the first line.
