A student was given the single matrix equation [43−84][xy]=[2035]. The student wrote the equations as 4x+8y=20 and 3x+4y=35. Use the rule about matrix equations to identify the student's mistake. What is the error in the first equation? A The coefficient with y should be −8. B The coefficient with y should be 4. C The coefficient with x should be −4. D The coefficient with x should be 8
