Given, 9x + 7/2 - {x - (x - 2/7)} = 36
=> 9x + 7/2 - {x - x + 2/7} = 36
=> 9x + 7/2 - {2/7} = 36
=> 9x + 7/2 - 2/7 = 36
=> 9x = 2/7 - 7/2 + 36
=> 9x = (2*2 - 7*7 + 36*14)/14
=> 9x = (4 - 49 + 504)/14
=> 9x = (508 - 49)/14
=> 9x = 459/14
=> x = 459/(9*14)
=> x = 51/14 {459 and 9 are divided by 9}
So, the value of x is 51/14
=> 9x + 7/2 - {x - x + 2/7} = 36
=> 9x + 7/2 - {2/7} = 36
=> 9x + 7/2 - 2/7 = 36
=> 9x = 2/7 - 7/2 + 36
=> 9x = (2*2 - 7*7 + 36*14)/14
=> 9x = (4 - 49 + 504)/14
=> 9x = (508 - 49)/14
=> 9x = 459/14
=> x = 459/(9*14)
=> x = 51/14 {459 and 9 are divided by 9}
So, the value of x is 51/14
