Also, indicate whether the given lines are independent, dependent, or inconsistent. Circle your final answer. (2 points each) 1) y = 4x - 1 8x - 2y = 6 2) 3x - 3y = 24 y=x-8 3) y = 2x - 1 6x + 3y = 1 Directions: Solve each system by using substitution or elimination. Write the solution as an ordered pair. Circle your final answer. (2 points each) 4) y = 2x - 49 x - y = 30 5) 15x + 2y = 25 3x + 3y = 44 Directions: Solve each system by using substitution or elimination. Write the solution as an ordered pair. Circle your final answer. (4 points each) 6) x + 2y - z = 1 3x - y - 2z = 19 5x + 3y - 3z = 16 7) 2x - y + z = - 4 3x + y - 2z = 0 3x - y =-4 8) x+y+z=3 2x + y + z = 5 x + 2y – z = 4 9) 4x – y + 2z = -6 -2x + 3y – z = 8 2y + 3z = -5 Directions: Solve the following system by using substitution or elimination.
