Gimana ini ka ?? Minta jawaban detil nya dong

a = -2 i -8 j +6 k
b = 5 i +4 j -5 k
c = 3 i +4 j -2 k

5d + 3a + 2b = 2c + 3d - 2b
5d - 3d = -3a -2b -2b +2c
2d = -3a -4b +2c
[tex] 2d = -3\left[\begin{array}{ccc}-2\\-8\\6\end{array}\right] -4\left[\begin{array}{ccc}5\\4\\-5\end{array}\right]+2\left[\begin{array}{ccc}3\\4\\-2\end{array}\right][/tex]
[tex] 2d = \left[\begin{array}{ccc}6\\24\\-18\end{array}\right] +\left[\begin{array}{ccc}-20\\-16\\20\end{array}\right]+\left[\begin{array}{ccc}6\\8\\-4\end{array}\right][/tex]
[tex] 2d = \left[\begin{array}{ccc}-8\\16\\-2\end{array}\right][/tex]
[tex] d = \left[\begin{array}{ccc}-4\\8\\-1\end{array}\right][/tex]

jadi d = -4i +8j -1k

jawab (B)
