Part C: Communication (8 Marks) 1. Consider the following system of equations: 3x - 5y = 20 3x + 5y = 8 a) To eliminate x, would you add or subtract? Explain. b) To eliminate y, would you add or subtract? Explain. 2. Jack and Jill both solved the given linear system: x + 2y = -5 3x - y =-1 Jill's answer was (1, 2) while Jack believes (-1, -2) is the right answer. Without solving (you can't use substitution or elimination), determine whose answer is correct. EXPLAIN your method and show your work
