​

Answer 1

$\huge{\underline{\underline{\red{\mathfrak{Answer:}}}}}$

$:⟹\dfrac{2}{7}(x - 9) = 3 - \dfrac{x}{3}$

$:⟹\dfrac{2x}{7} - \dfrac{18}{7} =3 - \dfrac{x}{3}$

$:⟹\dfrac{2x}{7} + \dfrac{x}{3} = \dfrac{3}{1} + \dfrac{18}{7}$

$:⟹\dfrac{6x + 7x}{21} = \dfrac{21 + 18}{7}$

$:⟹\dfrac{13x}{21} = \dfrac{39}{7}$

$:⟹13x = \dfrac{39}{7} \times 21$

$:⟹13x = 117$

$:⟹x = \dfrac{117}{13}$

$:⟹x = 9$
