The balance in the saving account before the deposit was $82.53

Let #a# be your balance after the deposit, #b# be the balance before the deposit and #d# be the amount of the deposit.

Then #a = b + d#

We know #a# = $319.23 and we know #d# = #236.70.

Substituting these into the equation gives:

$319.23 = #b# + $236.70

Solving for #b# while keeping the equation balanced gives:

$319.23 - 236.70 = #b# + $236.70 - $236.70

$82.53 = #b# + 0

#b# = $82.53
