On the first day of the year, you have $700 in your bank account. You spend $35 per week. Your friend starts the year with $450 in his bank account. He saves $15 per week.

Solve the equation 700 – 35w = 450 + 15w to find out how many weeks, w, it will take for you and your friend have the same amount of money in your accounts.

A number of weeks are 5.
So this is just a basic algebra equation where we need to solve for an unknown variable.

First we should put all the w's on one side and regular numbers on the other, so:

250  =  50w

If we divide by 50 on both sides, we get:

w  =  5

It will take 5 weeks for you and your friend to have the same amount of money in your back accounts.
