Firstly 190$is even so the number of 5$ is even and the number of 2$is a multiple of 5. So 5k lots of 2$
2n lots of 5$But if there are 4 less 5$ notes than 2$notes 5k – 4 = 2n Where 5k + 2n = 190$
Or k * 10$+ n * 10$ = 190$Then k+n = 19 Write n = 19 – k 5k – 4 = 38 – 2k 7k = 42 k = 6 n = 13 So we have 130$ Of 5$notes and 60$ of 2$notew that’s 26 5$ notes and 30 2\$ notes.
