Explanation:
Your unbalanced nuclear equation is

It is convenient to replace the question mark by an atomic symbol,
, where <em>x</em> = the atomic number, <em>y</em> = the mass number, and <em>Z</em> = the symbol of the element .
Then your equation becomes

The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
55 = <em>x</em> - 1, so <em>x</em> = 55 + 1 = 56
135 = <em>y</em> + 0, so <em>y</em> = 135
Element 56 is barium, so the nuclear equation becomes
