Show your work! 1) -2x+ y = -3 2x - 4y = 0 -2x+ y = -3 2x - 4y = 0 Substitution or Elimination Solution Solution 2) x + 2y = 6 x + 2y = 6 -6x - 3y = -9 -6x - 3y = -9 Substitution or Elimination Solution SolutionSolve the following application problem using a system of equations. 7) An auditorium sold 500 tickets for a play and raised $3400. Let x represent the number of adult tickets sold at $8 each and let y represent the number of student tickets sold at $5 each. Write and solve a system of equations to determine the number of adult tickets and the number of student tickets that were sold. Is ( 4, -3 ) a solution to the system? Is (-2, 6 ) a solution to the system? 8) 2x + 5y = -7 9 ) 3x - 2y =-18 x- y =7 -x+y=4
