bantu dong kakak kakak abg abg

( p-1 p+q ) + ( 1 0) = (1 0 1 -1 )
( p 2 ) ( -1 t) (0 0 0 1 )
( p-1 p+q) + ( 1 0 ) = (1 0 )
( p 2) (-1 t ) (0 1)

*(p-1) + 1 = 1 *(p+q) + 0 = 0 *2 + t = 1
p-1 = 1-1 1 + q = 0 t = 1-2
p-1 = 0 q = -1 t = -1
p= 1

jadi, q + 2 t = -1 + 2(-1)
= -1-2 = -3
Maaf, kalau salah!

Matriks
q = -1
t = -1
nilai q + 2t = (-1)+ 2(-1)= -1 - 2 = - 3
