Question

Tolong dong yang baik ini jawabannya apa pake cara nya yg bener yaa makasih ≧∇≦

Answer 1

1. x + 4 = -12
x = -12 - 4
x = -16

2. 5y = 4y + 10
5y - 4y = 10
y = 10

3. 2y + 15 = y
2y - y = -15
y = -15
4. 9p + 9 = 8p + 4
9p - 8p = 4 - 9
p = -5

5. 6p + 7 = 5p - 14
6p - 5p = -14 - 7
p = -21

6. (1/2)x + 3 = 9 -> Kedua ruas dikali 2.
x + 6 = 18
x = 18 - 6
x = 12

7. (1/3)x - 5 = 10
(1/3)x = 15
x = 15 × 3
x = 45

8. (1/4)y + 2 = 7
(1/4)y = 7 - 2
(1/4)y = 5
y = 5 × 4
y = 20

9. (1/4)x = 2/3
x = 2/3 × 4
x = 8/3

10. (3/4)x = -3/8
x = -3/8 × 4/3
x = -1/2
