Systems of equations can be solved algebraically by using the substitution method and the elimination method. Sometimes, one method is a better than the other. At other times, it is just as easy to use either method. For each system displayed below, decide whether it would be easier to solve the system using the substitution method, the elimination method or either method. Provide an explanation to support why you made your decision.

2x + 3y = 1

3x - 4y = 10

y = 3x - 4

2x + 3y = 10

x + 4y = 1

2x + 5y = -1
