Diberikan u=i+2j v=i+3j w=4i+3j tentukan nilai K, jika A. u+v+kW =(7,5) B. ku+3v-w = (2,13)

a.) u + v + k w = (7, 5)
(1,2) + (1,3) + k(4,3) = (7,5)
(2,5) + k(4,3) = (7,5)
k(4,3) = (5,0)
k = (5,0) / (4,3)

b.) ku + 3v - w = (2,13)
k(1,2) + 3(1,3) - (4,3) = (2,13)
k(1,2) + (3,9) - (4,3) = (2,13)
k(1,2) + (-1,6) = (2,13)
k(1,2) = (3,7)
k = (3,7) / (1,2)

semoga membantu
