1.Penyelesaian dari (2m - 1) : 3 = 5 adalah
2.Nilai A yang memenuhi 64 : (3k + 1) = 4 adalah ...
3. Nilai t yang memenuhi 13 x 4 + 5 = 10t - 3 adalah

Answer 1

3. 13 x 4 + 5 = 10t - 3
     57 = 10t - 3
57 + 3 = 10t
60 = 10t
60/10 = t
6 = t

Answer 2

1. (2m-1)/3 = 5
2m-1 = 3x5
2m-1 = 15
2m = 15+1
2m = 16
m = 16/2
m = 8

2. 64/(3k+1) = 4
64 = 4(3k+1)
64 = 12k + 4
64-4 = 12k
60 = 12k
k = 60/12
k = 5

3. 13 x 4 + 5 = 10t - 3
52 + 5 = 10t - 3
57 + 3 = 10t
t = 60/10
t = 6
