Question

How do you solve this ? what do you do with the exponets ?

Answer 1

$\bf \left( 6-x \right)^{\frac{4}{7}}=x^{\frac{4}{7}}\impliedby \begin{array}{llll} \textit{since the exponents are the same}\\ \textit{their bases must also be the same} \end{array} \\\\\\ 6-x=x\implies 6=2x\implies \cfrac{6}{2}=x\implies 3=x$

Answer 2

4/7 is the answer. 

I cant reall explain becuase it will take forever xD
