Question

996+11×{128×20÷5+[11707÷(720÷144+21×x)-14]-130}=5297

Answer 1

996+11*{2560:5+[11707:(5+21*x)-14]-130} = 5297
11*{512+[11707:(5+21*x)-14]-130} = 5297-996
11*{512+[11707:(5+21*x)-14]-130} = 4301
512+[11707:(5+21*x)-14]-130 = 4301:11
512+[11707:(5+21*x)-14]-130 = 391
512+[11707:(5+21*x)-14] = 391+130
512+[11707:(5+21*x)-14] = 521
11707:(5+21*x)-14 = 521-512
11707:(5+21*x)-14 = 9
11707:(5+21*x) = 9+14
11707:(5+21*x) = 23
11707 = 23*(5+21*x)
11707 = 115 + 483x
11707 - 115 = 483x
11592 = 483x
x = 11592 : 483
x = 24
