1) Suppose you invest money in two accounts. One of the accounts pays 4% interest annually, and the other account pays 5% interest annually. You have $ 2000 more invested in the account paying 4% than in the account paying 5%. How much do you have invested in the account paying 4% if you earn $ 670 interest in a year?

2) Money is invested in two accounts, twice as much in one paying 3% interest per year as in the other, which pays 4% interest per year. The total interest earned after one year is $140. If x is the amount invested at the 3% rate and the y is the amount invested at the 4% rate, then write a system of equations that will have a solution that gives the amount invested at each rate, and find the x and y
