WebJul 17, 2024 · Solution. We multiply the first equation by – 3, and add it to the second equation. − 3 x − 9 y = − 21 3 x + 4 y = 11 − 5 y = − 10. By doing this we transformed our original system into an equivalent system: x + 3 y = 7 − 5 y = − 10. We divide the second equation by – 5, and we get the next equivalent system. WebX = e t A. where. A = ( 1 − 2 − 2 1) There are different methods to find e t A. One way is to find two linearly independent vectors satisfying your. d V d t = A V. with initial values of ( 1, 0) and ( 0, 1) These vectors are then the columns of your matrix solution X = e t A.
