Here is your answer!

begingathered}given x = 3 = 2 times 3 - 2 \times (3) {}^{3} + 7 = 6 - 2 \times 27 + 7 = 6 - 54+ 7 = - 41\end{gathered}

= 2 times 3 - 2 \times (3) {}^{3} + 7 = 6 - 2 \times 27 + 7 = 6 - 54+ 7 = - 41\end{gathered} givenx=3

= 2 times 3 - 2 \times (3) {}^{3} + 7 = 6 - 2 \times 27 + 7 = 6 - 54+ 7 = - 41\end{gathered} givenx=3=2×3−2×(3)

= 2 times 3 - 2 \times (3) {}^{3} + 7 = 6 - 2 \times 27 + 7 = 6 - 54+ 7 = - 41\end{gathered} givenx=3=2×3−2×(3) 3

= 2 times 3 - 2 \times (3) {}^{3} + 7 = 6 - 2 \times 27 + 7 = 6 - 54+ 7 = - 41\end{gathered} givenx=3=2×3−2×(3) 3 +7

= 2 times 3 - 2 \times (3) {}^{3} + 7 = 6 - 2 \times 27 + 7 = 6 - 54+ 7 = - 41\end{gathered} givenx=3=2×3−2×(3) 3 +7=6−2×27+7

= 2 times 3 - 2 \times (3) {}^{3} + 7 = 6 - 2 \times 27 + 7 = 6 - 54+ 7 = - 41\end{gathered} givenx=3=2×3−2×(3) 3 +7=6−2×27+7=6−54+7
