Question

(81)−4÷(729)2−x=(9)4x

Answer 1

Answer:

→ $x = \dfrac {59041}{26973}$

SOLUTION :

→ (81) − 4 ÷ (729)2 − x = (9)4x

Removing the brackets,

→ $81 \: - \: 4 \: ÷ \: 729 \: × \: 2 \: - \: x \: = \: 9 \: × \: 4x$

→ 81 - $\dfrac {4}{729}$ × 2 - x = 9 × 4x

→ 81 - $\dfrac {4×2}{729}$ - x = 36x

→ 81 - $\dfrac {8}{729}$ - x = 36x

→ $\dfrac {59041}{729}$ - x = 36x

→ x = 36x - $\dfrac {59041}{729}$

→ - x - 36x = - $\dfrac {-59041}{729}$

→ - 37x = $\dfrac {-59041}{729}$

$x = \boxed{\dfrac {59041}{26973}}$
