Answer 1

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
