\(45:\left(3x-4\right)=3^2\)
\(\Rightarrow3x-4=45.3^2\)
\(\Rightarrow3x-4=405\)
\(\Rightarrow3x=409\)
\(\Rightarrow x=\frac{409}{3}\)
45 : (3x - 4) = 32
3x - 4 = 45 . 32
3x - 4 = 9
3x = 3
x = 9
\(45:\left(3x-4\right)=3^2\)
\(\Rightarrow3x-4=45:3^2\)
\(\Rightarrow3x-4=5\)
\(\Rightarrow3x=9\)
\(\Rightarrow x=3\)
\(45:\left(3x-4\right)=3^2\)
\(\Rightarrow\left(3x-4\right)=45:3^2=45:9=5\)
\(\Rightarrow3x=5+4=9\)
\(\Rightarrow x=9:3=3\)
Vậy \(x=3\)
