Given: initial deposit = 45 total deposit = 105 w = weekly deposit x = no. of weeks = 5 weeks y = amount in dollars 45 + 5w = 105 45 + 5w = 105 5w  = 105 - 45 5w =  60 w = 60/5 w = $12 weekly deposit. y = $45 + $12x   x = (y - 45)/12 To check: y = 45 + 12(5) y = 45 + 60 y = 105 total deposit in 5 weeks x = (105-45)/12 x = 60/12 x = 5 weeks I hope this help

6x + 55=133 this is the equation because u are adding $55 in the account for 6 weeks so that is how you get your answer.
