Gan ane tanya lagi  25-4y = 6y +15 itu caranya gmn si?ama  -4x – 15 =1 -8x tolong di respawn gan

25 – 4y = 6y + 15
25 – 15 = 6y + 4y
10 = 10y
1 = y

-4x – 15 = 1 – 8x
-4x + 8x = 15 + 1
4x = 16
x = 4

25 – 4y = 6y + 15
-4y – 6y = 15 – 25
-10y = -10
y = 1

-4x – 15 = 1 – 8x
-4x + 8x = 1 + 15
4x = 16
x = 4

Tapi maaf kalo salah
