MPM2D Unit 1: Linear Systems /23 Lesson 2 - Assignment 1. 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. 3) 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. [3 marks] b) Provide an explanation to support why you made your decision. [3 marks] 2x + 3y = 1 3x - 4y = 10 2x + 3y - 10 2x + by = -1 2. Solve each linear system using elimination. Verify your solution graphically or algebraically. [6 marks each] a) 2x + 5y = 16 y=x-1 bj 3x - 2y = 5 2x + 3y = 12 3. The Fraser's travelled 880 km from St. John's to Halifax. Part of the trip was by car at 80 km/h and the rest by ferry at 16 km/h. If the total travelling time for the trip was 27 hours, how many hours were spent by car and how many by ferry? [5 marks]
