Question

Tentukan penyelesaian persamaan berikut!
1. 2k=10 6. -r=2
2. 2b=1 7. 1/2s=3/2
3. 5m=30
4. 5d=0
5. 8e=-4

Answer 1

1. 2k = 10
maka
k = 5

2. 2b = 17
maka
b = 8.5

3. 5m = 30
maka
m = 6

4. 5d = 0
maka d = 0

5. 8e. =-4
maka
e = -2

6. -r=2
maka
r = -2

7. 1/2s = 3/2
maka
s = 3

Answer 2

1. 2k = 10
k = 10/2
jadi k = 5

2. 2b = 1
b = 1/2
jadi b = 1/2

3. 5m = 30
m = 30/5
jadi m = 6

4. 5d = 0
d = 0/5
jadi d = 0

5. 8e = -4
e = -4/8
jadi e = -2

6. -r = 2
jadi r = -2

7. 1/2s = 3/2
s = 3/2 : 1/2
s = 3/2 × 2/1
s = 6/2
jadi s = 3
