Sarah invests a total of RM 10,000 in three accounts, one paying 5% interest,
another paying 8% interest, and the third paying 9% interest. The annual interest
earned on the three investments last year was RM 770. The amount invested at 9%
was twice the amount invested at 5%. By using the Gaussian elimination method,
determine the value of investment for each rate.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F777214cf-6888-430a-a4d8-c1e2be7345fe%2F37b6e35e-f8aa-4fcd-8b5f-713b8ba8dcef%2Fnade69_processed.jpeg&w=3840&q=75)
