Tavion has $20 dollars in his bank account and needs $22 dollars for a new pair of socks. How much money does he need to get a new pair of socks?

This can be written as an algebra equation.

22 = 20+x, where x is the amount of money he needs

subtract 20, the amount he currently has, from both sides, and you get $2, the amount of money he needs to get the socks

He needs two more dollars for the socks
