Soal nomor 6

a. 5m/5n = 54
5m-n = 54
m-n = 4
Jika m = 9, 9 – n = 4
n = 5
(m,n) = (9,5)
Jika m = 8, 8 - n = 4
n = 4
(m,n) = (8,4)
Jika m = 7, 7 – n = 4
n = 3
(m,n) = (7,3)
Jika m = 6, 6 – n = 4
n = 2
(m,n) = (6,2)
Jika m = 5. 5 – n = 4
n = 1
(m,n) = (5,1)

b. Banyak himpunan penyelesaian ada 5

Soal nomor 7

2y = 22015 + 22014 + 22013/14
2y =22013 (22 + 2 + 1)/14
2y = 22013 x 7/14
2y = 22013/2
2y = 22012
y = 2012
