Question

Soal :
1. 9p + 9 = 8p + 4
2. 6p + 7 = 5p - 14
3. 3x + 8 = 4x - 5
4. 18x - 15 = 19x - 7
5. 14x - 10 = 15x + 7
jawablah dengan penyelesaian dari persamaan-persamaan

Answer 1

1. 9p + 9 = 8p + 4   
   9p-8p = 4-9
    p =-5

2. 6p + 7 = 5p - 14
    6p-5p = -14-7
        p = -21

3. 3x + 8 = 4x - 5
    8+5 = 4x-3x
        x =13

4. 18x - 15 = 19x - 7
      -15 + 7 = 19x-18x
           x =-8

5. 14x - 10 = 15x + 7
    -10 -7 = 15x-14x
       x =-17

Answer 2

1. 9p + 9 = 8p + 4
9p - 8p = 4 - 9
p = -5
2. 6p - 5p = -14 - 7
p = -21
3. 3x - 4x = - 8 - 5
- x = - 13
x = 13
4. 18x - 19x = -7 + 15
-x = 8
x = -8
5. 14x - 15x = 7 + 10
- x = 17
x = - 17
