Question

Jika 2(3x-1)+5 = 4(6x+7)-7 mempunyai penyelesaian x=n,berapakah nilai 10n+12?​

Answer 1

Jawab:

2

Penjelasan dengan langkah-langkah:

2(3x-1)+5 = 4(6x+7)-7

6x-2+5 = 24x+28-7

6x+3 = 24x+21

18x = -18

x = -1

10(-1)+12 = -10+12 = 2

Answer 2

2(3x-1)+5 = 4(6x+7)-7

6x-2+5 = 24x+28-7

6x+3 = 24x+21

6x-24x = 21-3

-18x = 18

x = 18/-18

x = -1

x=n=-1

10n+12

= 10 × (-1) + 12

= -10 + 12

= 2

maaf kalau ada salah hitung, semoga membantu
