Question

Tolong ya kerjakan menggunakan cara equivalent dan algoritma
soal :
1. -4a -8 = -8a
2. -2b + 8 = 4 b - 12
tlng yak dikumpul bsk !

Answer 1

1. - 4a - 8 = - 8a
- 4a + 8a = 8
4a = 8
  a = 2

2. - 2b + 8 = 4b - 12
4b + 2b = 8 + 12
6b = 20
b = 20/6 = 10/3

Answer 2

1. -4a - 8= -8a
-8 = -8a+4a
-8 = -4a
a = 2
2. -2b +8 = 4b - 12
8 +12 = 4b + 2b
20 = 6b
b = 20/6 atau 10/3
