= 6(√12+√27) / 12-27
= 6(√12+√27) / -15 ------ atas dan bawah dibagi 3
= 2(√12+√27) / -3
= -2/3√12 - 2/3√27 ------ √12 dan √27 bisa disederhanakan
= -2/3 √4x3 - 2/3√9x3
= -4/3√3 - 2√3
21) 4(x-12) = 2x - 20
4x - 48 = 2x - 20
4x - 2x = -20 + 48
2x = 28
x = 28/2 = 14
22) 5(x+6) +12 -3(x-6) = 4(x-1)
5x+30+12 -3x+18 = 4x - 4
5x-3x + 30+12+18 = 4x-4
2x +60 = 4x - 4
60+4 = 4x-2x
64 = 2x
x = 64/2 = 32
aku taunya cuma yg itu,, maaf, semoga membantu
