Hari and Farid have $120. Hari and Peter have$230. Peter has 6 times as much money as Farid. How much money does Hari have?

Sagot :

let H=money of Hari
let F=money of Farid
let P=money of Peter
H+F=120
H+P=230
P=6F
Using elimination
H+F=120
H+6F=230
Subtracting the two equations=
5F=110
F=22
Substituting value of F
H+F=120
H+22=120
H=98
