(x-8)+4=3(2x+7)-9 tolong jawab dengan benar

( x - 8 ) + 4 = 3 ( 2x + 7) - 9
x - 8 + 4 = 6x + 21 - 9
x - 4 = 6x + 12
x - 6x = 12 + 4
- 5x = 16
x = - 16/5

(x-8)+4=3(2x+7)-9
4x-32  = 6x+21-9
4x-32  = 6x+12
4x-6x  =12+32
-2x      = 44
     x     = [tex] \frac{44}{-2} [/tex]
     x     = -22
maaf kalau salah
