Section 3.1 Systems of Linear Equations in Two Variables 1. Given a system of linear equations, explain at least two different methods of solving that system. (2 points) 2. Determine whether the given ordered pair (-6, 1) is a solution of a system of linear equations. (2 points) - 3x - 5y = 13 - x +4y = 10 3. Solve each system using the substitution method. Express your final answer in solution set form. (3 points) x - 0.2y = 1 - 10x + 2y = 5 (3 points) Sx+ zy =16 " x + zy= 9 4. Solve each system using the addition/elimination method. Express your final answer in solution set form. (3 points) - x+2y =-1 5x - 10y = 6
