tentukan himpunan penyelsaian dari persaman linear berikut. 25 - 4y = 6y + 15

2
25 - 4y = 6y + 15
cara nya
25 - 4y = 6y + 15
-4y - 6y = 15 - 25
- 10y = - 10
y = -10 : - 10 = 1
25y - 4y = 6y + 15
25 - 4y = 6y + 15
25 - 25 - 4y= 6y + 15 - 25
- 4y = 6y + (-10)
-4y - 6y = -10
- 10y = - 10
y = -10 : -10
y = -1

25-4y = 6y+15
25-15 = 6y + 4y
10 = 10y
10/10 = y
 1 = y
jd HP { 1 }

⇔ 25-4y  = 6y+15
⇔ 25-15  = 6y+4y
⇔ 10       = 10y
⇔ y          =10:10
⇔ y          =     1
Hp={1}
