Answer:
$106
Step-by-step explanation:
Before making the deposit, she had x.
Then she added the deposit and ended up with $264.
If she added $26 to the original amount in the account, that is x + 26.
If she doubled it, it would be 2(x + 26).
This would equal the new amount, $264.
2(x + 26) = 264
2x + 52 = 264
2x = 212
x = 106
