It is difficult to answer this question definitively, as the difficulty of a subject is subjective and can vary from person to person. Generally speaking, linear algebra is considered to be a more abstract subject than differential equations, and thus may be more difficult for some people to understand. However, some people may find differential equations more difficult due to the complexity of the equations and the need to understand calculus in order to solve them. Ultimately, the difficulty of either subject will depend on the individual.
