Answer 7

treat the top numbers and the bottom numbers as separate equations. both need to be balanced.

in this case, notice how the top row is

185 --> 4 + ___

(fill in the blank with the appropriate number that makes the sum equal on both sides)

same logic with the bottom row

79 ---> 2 + ___

once you have both numbers, you should have something like

\[_{a}^{b}X\] with b being the top # and a being the bottom #. to find the chemical symbol X, simply use the bottom number (a) to find the appropriate element on the periodic table.
