b,(x-12)-15=(20-7)-(18+x)
1.Tìm các số nguyên x:
5/17+-4/9+-20/31+12/17+-11/31<x<=-3/7+7/15+4/-7+8/15+2/3
2. Tính
A=5-10/19+15/143-5/81+8-16/26+24/243-8/181
6-12/19+18/143-6/81+9-18/26+27/243-9/181
a,25+[x+17]=0 ; b'20-[x+12]=0 ; c, 15+[5-x]=-7 ; d, 3-5+[-x+3]=6 ; e, 25-[30+x]=x-[27-8] ; f, [x-12]-15=[20-7]-[18+x]
a) -2 (x+6)+6 (x-10)=8
b) ( x-12)-15=(20-7) - (18-x)
c)2(5+3x)+x=31
d) -x (x+7) ( x-4) =0
