\(\Rightarrow4x+8-3+6x=7-2x-2\)
\(\Rightarrow4x+6x+2x=-8+3-2\)
\(\Rightarrow12x=-7\)
\(\Rightarrow x=\frac{-7}{12}\)
Vậy \(x=\frac{-7}{12}.\)
bạn hoàng thị ngọc ánh làm sai rồi
\(4.\left(x+2\right)-3\left(1-2x\right)=7-2\left(x+1\right)\)
\(\Rightarrow4x+8-3-6x=7-2x-2\)
\(\Rightarrow4x+2x-6x+8-3=5\)
\(\Rightarrow6x-6x+8=5+3\)
\(\Rightarrow6x-6x=8-8\)
\(\Rightarrow6x-6x=0\)
