Question

Tolong di jawab..

pakai cara yaa!

Answer 1

Jumlah setiap baris/kolom adalah 12 + 10 + 8 = 30

maka

*) 9 + 8 + R = 30

R = 30 - 17

R = 13

*) M + 10 + 6 = 30

M = 30 - 16

M = 14

*) K + M + 9 = 30

K + 14 + 9 = 30

K = 30 - 23

K = 7

*) K + 12 + N = 30

7 + 12 + N = 30

N = 30 - 19

N = 11

MAKA

(K - M x N) : R

= (7 - 14 x 11) : 13

= (7 - (14 x 11)) : 13

= (7 - 154) : 13

= - 147/13
