Answer 1

1)  4n = 4
     n = 4 : 4
       = 1
2)  3p = 2
     p = 2 : 3
        = 0.6
3)  5f = 3
     f = 3 : 5
       = 0.6
4)  6q = - 48
     q = - 48 : 6
       = - 8
5)  7r = - 3
     r = - 3 : 7
       = 0.4
6) - 3s = 1
     s  = 1 : - 3
         = 0.3
7)  2/3t = 8
       t = 8 x 3 : 2
         = 12
8)  -4/5x = 16
     x = 16 x 5 : -4
       =  - 20
9)  x/4 = 5
       x = 5 x 4
           = 20
10)  y/2 = -1
       y = -1 x 2
          = -2

#semoga membantu, sorry nggak semuanya...

Answer 2

1. 4n = 4
n = 4/4
n = 1

2. 3p = 2
p = 2/3

3. 5f =3
f = 3/5
f = 6/10
f = 0,6

4. 6q = -48
q = -48/6
q = -8

5. 7r = -3
r = -3/7

6. -3s = 1
s = 1/-3
s = -1/3

7. 2/3t = 8
t = 8 : 2/3
t = 8 × 3/2
t = 24/2
t = 12

8. -4/5x = 16
x = 16 : -4/5
x = 16 × -5/4
x = -80/4
x = -20

9. x/4 = 5
x = 5 : 1/4
x = 5 × 4/1
x = 20

10. y/2 = -1
y = -1 : 1/2
y = -1 × 2/1
y = -2

11. u/6 = 0
u = 0 : 1/6
u = 0

12. 3/4a = -6
a = -6 :3/4
a = -6 × 4/3
a = -24/3
a = -8

13. -w/5 = -6
-w = -6 :1/5
-w = -6 × 5/1
w = 30

1. -7z = 3z - 30
-7z -3z = -30
-10z = -30
z = 30/10
z = 3

2. 4d + 6 = d
4d - d = -6
3d = -6
d = -6/3
d = -2

3. 6m - 2 = 2m - 8
6m - 2m = -8 + 2
4m = -6
m = -6/4
m = -1 2/4
m = -1 1/2

4. 3t + 6 = 6t + 7
3t - 6t = 7-6
-3t = 1
t = -1/3

semoga membantu
