  • Pregunta: Use Cramer's rule to solve each system of equations. If D = 0, then use another method to determine the solution set. See Examples 5-7. 63. x + y = 4 2x - y = 2 64. 3x + 2y = -4 2x - y = -5 65. 4x + 3y = -7 2x + 3y = -11 66. 4x - y = 0 2x + 3y = 14 67. 5x + 4y = 10 3x - 7y = 6 68. 3x + 2y = -4 5x - y = 2 69. 1.5x + 3y = 5 2x + 4y=3 70. 12x + 8y = 3 1.5x + y
