Answer 1

`25+(9x-5):2 = 3^3`

`25+(9x-5):2 = 27`

`(9x-5):2 = 27-25`

`(9x-5):2 = 2`

`9x-5 = 2 x 2`

`9x -5=4`

`9x=4+5`

`9x=9`

`x=9:9`

`x=1`

Answer 2

\(25+\left(9x-5\right):2=3^3\\ \Rightarrow25+\left(9x-5\right):2=27\\ \Rightarrow\left(9x-5\right):2=27-25=2\\ \Rightarrow9x-5=2.2=4\\ \Rightarrow9x=4+5=9\\ \Rightarrow x=9:9=1\)

Answer 3

\(25+\left(9x-5\right):2=3^3\\ 25+\left(9x-5\right):2=27\\ \left(9x-5\right):2=27-25\\ \left(9x-5\right):2=2\\ \left(9x-5\right)=2.2\\ \left(9x-5\right)=4\\ 9x=4+5\\ 9x=9\\ x=9:9\\ x=1.\)
