Question 723511
x+y = 6000 is your first equation since the sum of the two amounts invested must be $6,000


0.05x + 0.09y = 380 is your other equation since you earn 0.05x dollars in interest in the first account and 0.09y dollars in interest in the second, so they total to 0.05x + 0.09y, which is exactly $380 in interest
