Question

(9x+7) /2-[x-(x-2) /7]=36​

Answer 1

Question

(9x+7)/2 - [x - (x-2)/7]=36

Solution

$= \frac{(9x + 7)}{2} - (x - \frac{(x - 2)}{7} ) = 36 \\ = \frac{(9x + 7)}{2} - (\frac{ 7x - x + 2)}{7} = 36 \\ = \frac{(9x + 7)(7) - (6x + 2)(2)}{14} = 36 \\ = \frac{63x + 49 - 12x - 4}{14} = 36 \\ = 51x + 45 = 36 \times 14 \\ = 51x = 504 - 45\\ = x = \frac{459}{51} \\ = x = 9$

______________________________

Therefore, value of 'x' is 9.
