\(27+288\div9x-302=35\)
\(27+288\div9x=337\)
\(288\div9x=310\)
\(9x=\dfrac{144}{155}\)
\(x=\dfrac{16}{155}\)
\(27+288\div\left(x-3\right).2=35\)
\(27+288\div\left(x-3\right)=17,5\)
\(288\div\left(x-3\right)=17,5-27\)
\(288\div\left(x-3\right)=-9,5\)
\(288\div\left(x-3\right)=\dfrac{-19}{2}\)
\(x-3=\dfrac{576}{19}\)
