2(x-4)+(3-x)=12
(2x-8)+(3-x)=12
6x-2x²-24+8x=12 terus dijabarin lagi
2014-01-18T08:48:26+07:00
2(X-4)+(3-X)=12
2X- 8  +3-X = 12
2X+3X = 12+8
5X= 20
X= 20/5
X= 4

2(x-4)=(3-x)
2(x-4)+(3-x)= 12-------------> 2x-8+3-x =12 ------------> 2x-x-8+3=12---------->x-5 =12 pindah ruas x=12+5-------> x=17
makasih ya kak.......
