1. 5a - 2 = 3a - 8 2. x - 2 =3 (x + 6) 3. 2(x+1) = 3(2x-1) 4. 5(x-2) + 3 = 3(2x-1)

Ini satu sampai empat, tapi saya agak ragu yang nomer tiga

1. 5a-2 = 3a-8
5a-3a = -8+2
2a = -6
a = -6/2
a = -3
2. x-2 = 3(x+6)
x-2 = 3x+18
x-3x = 18+2
-2x = 20
x = 20/-2
x = -10
3. 2(x+1) = 3(2x-1)
2x+2 = 6x-3
2x-6x = -3 -2
-4x = -5
x = -5/-4
4. 5(x-2) +3 = 3(2x-1)
5x-10+3 = 6x-3
5x-7 = 6x-3
5x-6x = -3+7
-x = 4
x = -4
maaf jika salah
