Nomor 10 dong. Tentabg matriks. Makasi

A = 2B^t
(a ...... 4) = 2 (2c - 3b ............. a)
(2b .. 3c) ..... (2a + 1 ......... b + 7)

(a ........ 4) = (4c - 6b ........... 2a)
(2b ... 3c) .. (4a + 2 ..... 2b + 14)

Baris 1 kolom 2
4 = 2a => a = 2

Baris 2 kolom 1
2b = 4a + 2
2b = 4(2) + 2
b = 5

Baris 2 kolom 2
3c = 2b + 14
3c = 2(5) + 14
c = 8
