Penjelasan dengan langkah-langkah:
1.
x/2 - 2x/5 = -1 disamakan penyebut
5x/10 - 4x/10 = -1
x/10 = -1
x = -10
2.
2x/3 - 1/2 = 5x/6 + 2
2x/3 - 5x/6 = 1/2 + 2
4x/6 - 5x/6 = 5/2
-x/6 = 5/2
-x = 15
x= -15
3.
(x-3)/2 = -4
x-3 = -8
x = -5
4.
(x+2)/6 = (x-3)/4
4(x+2) = 6(x-3)
4x + 8 = 6x - 18
4x - 6x = -8 - 18
-2x = -26
x = 13
