I have a total of 17 bills in my wallet. ● The value of all the money in my wallet is $180. ● I have twice as many $5 bills as I do $10 bills. Write a system of 3 linear equations to represent this situation and then use matrices to solve for x, th number of $5 bills, y, the number of $10 bills and z, the number of $20 bills in his wallet.
