May someone please help me with #1, #3, #7, #9, #11 and #19? Thank you so much, I truly appreciate you!!#1) x - 3y = -14x + 3y = 11#3) x + 4y = 7 1/2x + 2y = 5#7) 2x - 5y = 106x - 15y = 30#9) 4x - 5y = 142x + 3y = -4 #11) 2x - 3y = 6 6x - 9t = 12 #19) 2x - y = 34x + ky = 4

2.1 - In Exercises 1, 3, 7, 9, 11 determine whether each system of linear equations has (a) one and only one solution, (b) infinitely many solutions, or (c) no solution. Find all solutions whenever they exist. x - 3y = -1 1. 4x + 3y = 11 3. x + 4y = 7 2x - 5y = 10 Ax + 2y = 5 7 . 6x - 15y = 30 4x - 5y = 14 2x - 3y = 6 9. 2x + 3y = -4 11. 6.x - 9y = 12 19. Determine the value of k for which the system of linear equations 2x - y = 3 4x + ky = 4 has no solution
