Kak tolong pake caranya carabuat menyatukan 1/2u dan 1/3u .kalo dipindah ruas kekanan jadi dikali atau dibagi atau ditambah atau dikurang .tolong no 3 ,4 , 5 n

No 3.
1/2x - 4 = 1/3x - 2
(1/2 x - 4 = 1/3x - 2) 6
3x - 24 = 2x - 12
3x - 2x = -12 + 24
x = 12

No.4.
(y - 7)/2 - 1/3 = (y - 7)/3
{(y - 7)/2 - 1/3 = (y - 7)/3} 6
3(y - 7) - 2 = 2(y - 7)
3y - 21 - 2 = 2y - 14
3y - 2y = -14 + 21
y = 7

No.5.
(-5x + 2)/3 = x + 2
{(-5x + 2)/3 = x + 2} 3
-5x + 2 = 3(x + 2)
-5x + 2 = 3x + 6
-5x -3x = 6 - 2
-8x = 4
x = 4/-8
x = -1/2
