You have $22 in your bank account and deposit $11.50 each week. at the same time your cousin has $218 but is withdrawing $13 each week. when will your accounts have the same balance? (hint: write a system for the situation and solve)

You = 22 + 11.50w
Cousin = 218 - 13w

it wants to know what w equals when You = Cousin
or
22 + 11.50w = 218 - 13w

first we can add 13w to both sides
24.50w + 22 = 218

then we can subtract 22 from both sides 
24.50w = 196

then we divide both sides by 24.50
so
w = 196 / 24.50 = 8

therefore it would take 8 weeks for the accounts to have the same balance
