Answer 1

$6x = 9 \\ \\ x = \frac{9}{6} \\ \\ x = \frac{3}{2} \\ \\ \boxed{\boxed{\boxed{x = 1,5}}}$

Answer 2

$\large\bm{6x = 9} \\ \large\bm{}6x \div 6 = 9 \div 6 \\ \large\bm{}x = 9 \div 6 \\ \\ \large\bm{}x = \dfrac{9}{6} \\ \\ \large\bm{}x = \dfrac{9 \div 3}{6 \div 3} \\ \\ \large\bm{}x = \dfrac{3}{2} \\ \\ \bm{\large\boxed{\boxed{  { \large \bm{ x = 1 ,5}}}}}$
