18=5x-3x
18=2x
2x=18
x=18/2
x=9
b)3(2x-2)=4x+8
6x-6=4x+8
6x-4x=8+6
2x=14
x=14/2
x=7
c)2(x-3)=x-1
2x-6=x-1
2x-x=-1+6
x=5
(maaf kalau salah tapi kayaknya itu dah benar semua)
- 2x = - 18
x = 9
B) 6x - 6 = 4x + 8
6x - 4x = 8 + 6
2x = 14
x = 7
C) 2x - 6 = x - 1
2x - x = - 1 + 6
x = 5
Kalo salah maaf yaak
