Expert Answer

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.

 According to law of conservation of atomic number and mass number

90 = 82 + 2x y

2x - y = 8 .................(1)

232 = 208 + 4x

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '. ................(2)

From (1) & (2)

2 (6) -y = 8

12 - 8 = y

or Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.
