(B + 156) ÷ 9 + ( 219 + 437 ) ÷ 8 = (164+472)÷4
(B + 156 ) ÷ 9 + ( 219 + 437 ) ÷ 8 = 636 ÷ 4
(B + 156 ) ÷ 9 + ( 219+437 ) ÷ 8 = 159
(B + 156 ) ÷ 9 + 656 ÷ 8 = 159
(B + 156 ) ÷ 9 + 82 = 159
(B + 156 ) ÷ 9 = 159 - 82
(B + 156 ) ÷ 9 = 77
(B + 156 ) = 77 * 9
B + 156 = 693
B = 693 - 156
B = 537
(537 + 156) ÷ 9 + ( 219 + 437 ) ÷ 8 = (164+472)÷4
159 = 159
ответ: В = 537
