Question

Jika x adalah bilangan asli tentukanlah himpunan penyelesaiannya
1. 6x + 5 = 26-x
2. x - 12 = 2x + 36
3. -5x - 4x +10 =1
gue berani ngasih poin yang besar.

Answer 1

1. 6x + 5 = 26 - x
6x + x = 26 - 5
7x = 21
x = 21/7 = 3

2. x - 12 = 2x + 36
x - 2x = 36 + 12
- x = 48
x = - 48

3. - 5x - 4x + 10 = 1
- 9x = - 9
x = 1

Answer 2

No 1
6x + 5= 26 - x
6x + x= 26 - 5
7x= 21
x= 21/7
x= 3

Hp= {3}

No. 2
x - 12= 2x + 36
x - 2x= 36 + 12
-x= 48
x= -48

Hp= {-48}

No. 3
-5x - 4x + 10= 1
-9x + 10= 1
-9x= 1 - 10
-9x= -9
x= -9/-9
x= 1

Hp= {1}

Catatan :
Hp= himpunan penyelesaian
