5 × { 3 + 4 × [ 1 + 2 × ( x/9 - 4 ) ] } + 11 = 46
5 × [ 3 + 4 × ( 1 + 2x/9 - 8 ) ] + 11 = 46
5 × [ 3 + 4 × ( - 7 + 2x/9 ) ] + 11 = 46
5 × ( 3 - 28 + 8x/9 ) + 11 = 46
5 × ( - 25 + 8x/9 ) + 11 = 46
- 125 + 40x/9 + 11 = 46
- ( - 125 - 11 ) + 40x/9 = 46
- 114 + 40x/9 = 46 | × 9
- 1026 + 40x = 414
40x = 414 + 1026
40x = 1440
x = 1440 : 40
x = 36
