\(2\left(x+3\right)+\left[38-\left(12-9\right)^3\right]=2\left(x+1\right)+8^3\)
\(2x+6+\left[38-3^3\right]=2x+1+512\)
\(2x+6+11=2x+513\)
\(2x+17=2x+513\)
\(2x-2x=513-17\)
\(0x=496\)
\(\Rightarrow\) Không có x thảo mãn.
\(2\left(x+3\right)+\left[38-\left(12-9\right)^3\right]=2\left(x+1\right)+8^3\)
\(\Rightarrow2x+6+38-3^3=2x+2+8^3\)
\(\Rightarrow2x-2x=2+8^3-6-38-3^3\)
\(\Rightarrow0x=2+8^3-6-38-3^3\) (vô lí)
Vậy, pt vô nghiệm
