2 - 3 ( 1 - 2x ) = 5 - ( 2x + 4 ) berapa hasilnya??

2-3(1-2x)=5-(2x+4)
-1(1-2x)=5-(2x+4)
-1+2x=(-10x)-20
2x+10x=(-20)+1
12x=(-19)
x=(-19/12)
.
2-3(1-2x)=5-(2x+4)
-1(1-2(19/12))=5-(2(19/12)+4)
-1(1-(19/6))=5-((19/6)+4)
-1+19/6=(-95/6)-20
=(-95/6)-20+1-(19/6)
=(-144/6)-19
=(-19)-19
=(-38)
.
semoga membantu.
