R tranpose = T T = ( -3a a-2b) ( b+c 2d+c) (e-2d e-3f) R tranpose = (8 2) (4 10) (0 -1) jadi nanti T = R tranpose bentuknya kaya diatas ini. maka penghitungannya : -3a = 8 a = -8/3
a - 2b = 2 -8/3 - 2b = 2 -2b = 2 + 8/3 -2b = 14/3 b = 14/3 : (-2) b = -7/3
b + c = 4 -7/3 + c = 4 c = 4 + 7/3 c = 19/3
2d + c = 10 2d + 19/3 = 10 2d = 10 - 19/3 2d = 11/3 d = 11/3 : 2 d = 11/6
e - 2d = 0 e - 11/3 = 0 e = 11/3 (Catatan --> itu tadi kenapa 2d dapat 11/3 ga 11/6? Karena tadi yang penghitungan d kan udah ada yang 2d = 11/3. tapi kalo mau dikalikan 2.11/6 juga sama kok hasilnya kalo disederhanakan)
e - 3f = -1 11/3 - 3f = -1 -3f = -1 - 11/3 -3f = -14/3 f = -14/3 : (-3) f = 14/9
Semoga Membantu!! Selamat dan Semangat Belajar!!

Tingkat SMA ya? kalo iya, Matematika udah sampe bab apa?
T = ( -3a a-2b)
( b+c 2d+c)
(e-2d e-3f)
R tranpose = (8 2)
(4 10)
(0 -1)
jadi nanti T = R tranpose bentuknya kaya diatas ini.
maka penghitungannya :
-3a = 8
a = -8/3
a - 2b = 2
-8/3 - 2b = 2
-2b = 2 + 8/3
-2b = 14/3
b = 14/3 : (-2)
b = -7/3
b + c = 4
-7/3 + c = 4
c = 4 + 7/3
c = 19/3
2d + c = 10
2d + 19/3 = 10
2d = 10 - 19/3
2d = 11/3
d = 11/3 : 2
d = 11/6
e - 2d = 0
e - 11/3 = 0
e = 11/3
(Catatan --> itu tadi kenapa 2d dapat 11/3 ga 11/6? Karena tadi yang penghitungan d kan udah ada yang 2d = 11/3. tapi kalo mau dikalikan 2.11/6 juga sama kok hasilnya kalo disederhanakan)
e - 3f = -1
11/3 - 3f = -1
-3f = -1 - 11/3
-3f = -14/3
f = -14/3 : (-3)
f = 14/9
