Question

92 – 7.(3x + 52)= 8^6 : 8^4 nhanh=tick

Answer 1

92 – 7.(3x + 52)= 8⁶ : 8⁴

92-21x-364=8^6-4

92-21x-364=8²

92-21x-364=64

-21x=64-92+364

-21x=336

x=336:(-21)

x=-16

Answer 2

\(92-7.\left(3x+52\right)=8^6:8^4\\ \Leftrightarrow92-21x-364=8^2\\ \Leftrightarrow-21x=64-92+7.52\\ \Leftrightarrow-21x=336\\ \Leftrightarrow x=\dfrac{336}{-21}=-16\)

Answer 3

\(92-7.\left(3x+52\right)=8^6:8^4\)

\(92-21x-364=64\)

\(-21x=64+364-92\)

\(-21x=336\)

\(x=\dfrac{336}{-21}\)

\(x=-16\)

Answer 4

92 – 7.(3x + 52)= 8⁶ : 8⁴

92-21x-364=8^6-4

92-21x-364=8²

92-21x-364=64

-21x=64-92+364

-21x=336

x=336:(-21)

x=-16
