We have here that Roberto has a total of $3300 in two savings account.
Then, if y represents the amount in one account, we have that the sum of both accounts is up to $3300.
We can suppose that the other account is x. Then, we have:
[tex]x+y=\$3300[/tex]
If we subtract y from both sides of the equation, we have:
[tex]x+y-y=\$3300-y\Rightarrow x=\$3300-y[/tex]
Therefore, the algebraic expression for the amount in Roberto's other account is (since x is not mentioned, we have):
[tex]\$3300-y[/tex]
In summary, the amount in Roberto's other account is $3300 - y.
