Tolong bantuin yaa pake cara;)
Tentukan persamaan berikut:
1) 8x - 35 = 3x
2) 25 - 3y = 3y + 1
3) 3x - 5x + 9 = 29- 4x -12
4) 8z + 6-z = 4 + 3z + 2
5) m-12 =7m-6
Bantuin yaa makasih sebelumnya

8x - 3x = 35
5x = 35
x = 35/5
x = 7
2) 25 - 3y = 3y + 1
25 - 1 = 3y + 3y
24 = 6y
24/6 = y
4 = y
y = 4
3) 3x - 5x + 9 = 29 - 4x - 12
3x - 5x + 4x = 29 - 12 - 9
2x = 8
x = 8/2
x = 4
4) 8z + 6 - z = 4 + 3z + 2
8z - z - 3z = 4 + 2 - 6
4z = 0
z = 0/4
z = 0
5) m - 12 = 7m - 6
m - 7m = -6 + 12
-6m = 6
m = 6/-6
m = -1
