ini kak terimakasih banyak semoga di jawab kak

K(-t + 3) = (4t + 2) / (1 - t)

p = -t + 3
Maka t = 3 - p

K(p) = (4 [3 - p] + 2) / (1 - [3 - p] )
K(p) = (12 - 4p + 2) / ( -2 + p )
K(p) = (14 - 4p) / ( -2 + p )

K(t + 3) = (14 - 4 [t + 3] ) / ( -2 + t + 3)
K(t + 3) = (14 - 4t - 12) / (t + 1)
K(t + 3) = (2 - 4t) / (t + 1)

K(a) =(14 - 4a) / ( -2 + a)
2 = (14 - 4a) / ( -2 + a)
2(-2 + a) = 14 - 4a
-4 + 2a = 14 - 4a
6a = 18
a = 3
