37.) 2y-4=11-y
2y+y=11+4
3y =15
y =15:3
y =5
jawabannya adalah B.y=5
maaf hanya bisa jawab itu saja...

Nomor 36 :
5 (7x - 3) - 3 (7x - 3) = x + 7
35x - 15 - 21x + 9 = x + 7
14x - 6 = x + 7
14x - x = 7 + 6
13x = 13
x = 13/13 = 1 --> Opsi D

Nomor 37
2y - 4= 11 - y
2y + y = 11 + 4
3y = 15
y = 15/3 = 5 --> Opsi B.

Nomor 38 :
(2m - 1) / 3 = 5
2m - 1 = 15
2m = 16
m = 16/2 = 8 --> Opsi B

Nomor 39 :
64 / (3k + 1) = 4
64 = 12k + 4
12k = 60
k = 60/12 = 5 ---> Opsi D.

Nomor 40 :
13 x 4 + 5 = 10t - 3
52 + 5 = 10t - 3
57 = 10t - 3
10t = 60
t = 60/10 = 6 ---> Opsi A.
