In july, kimberly made two deposits i her bank account. She made no withdrawals. At the end of July, her account balance was 120.62. Write and solve an equation to find kimberly's balance at the end of july

Doesn't seem as tho' this question is complete. First of all, you don't mention interest. Second, you don't measure how large the deposits are.

If you represent the 2 deposits with "x" and "y," then x + y = $120.62. This cannot be solved for either x or y without further information.
