Question

5x+x=39-3^11:3^9

Answer 1

\(5x+x=39-3^{11}:3^9.\)

\(5x+x=39-9\)

\(5x+x=30\)

\(\Leftrightarrow x.\left(5+1\right)=30\)

\(x.6=30\)

\(\Rightarrow x=5\)

Answer 2

\(5x+x=39-3^{11}:3^9\)

\(6x=39-3^2\)

\(6x=39-9\)

\(6x=30\)

\(x=30:6\)

\(x=5\)

Vậy \(x=5\)

Tham khảo nhé~

Answer 3

\(5x+x=39-3^{11}:3^9\)

\(5x+x=39-9\)

\(5x+x=30\)

\(\Rightarrow5x+1x=30\)
