Melanie saves $20 every month in her savings account. She withdrew $60 one time to go shopping. She now has $280 in her account. write and solve an equation to determine how many months she has been saving up

20x-60=280

So x for unknown amount of months, since 20 dollar each month 20x

-60 becuase she withdraws 60 one time

=280 becuase thats what she has left

x=17

17 months
