\(B=\frac{x^2+x+1}{x}=\frac{7}{2}\)

\(\frac{x^2+x+1}{x}-\frac{7}{2}=0\)

\(\frac{x^2+x+1}{x}-\frac{3,5x}{x}=0\)

\(\frac{x^2-2,5x+1}{x}=0\)<=> \(x^2-2,5x+1=0\)

\(\left(\frac{x}{2}-1\right)\left(2x-1\right)=0\)

Th1: x/2 -1 = 0 <= > x = 2

TH2: 2x - 1 = 0 < = > x = 1/2

Vậy x thuộc {1/2 ;  2}

**** x 9 = 2118*

< = > 2118* chia hết cho 9 < = > 2118* = 21186

< = > **** = 21186 : 9 = 2354

Vậy ta có 2354 x 9 = 21186

x+5=10

=> x=10-5=5 hoặc x=-10-5=-15

x-6=17

=>x=17+6=23 hoặc x=-17+6=-11

x*7=49

=>x=49/7=7 hoặc x=-49/7=-7

x/8=3

=>x=3*8=24 hoặc x=-3*8=-24
