200 : (((7 + 144 : х) + 132) · 5 - 600) = 2
((7 + 144 : х) + 132) · 5 - 600 = 200 : 2
((7 + 144 : х) + 132) · 5 - 600 = 100
((7 + 144 : х) + 132) · 5 = 100 + 600
((7 + 144 : х) + 132) · 5 = 700
(7 + 144 : х) + 132 = 700 : 5
(7 + 144 : х) + 132 = 140
7 + 144 : х = 140 - 132
7 + 144 : х = 8
144 : х = 8 - 7
144 : х = 1
х = 144 : 1
х = 144

Проверка:
200 : (((7 + 144 : 144) + 132) · 5 - 600) = 2
200 : (((7 + 1) + 132) · 5 - 600) = 2
200 : ((8 + 132) · 5 - 600) = 2
200 : (140 · 5 - 600) = 2
200 : (700 - 600) = 2
200 : 100 = 2
2 = 2
