A bank teller has 35 bills in $5,$10, and $20 denominations. The total value from these bills is $370. The total number of $10 bills and $20 bills is 7 more than the number of $5. How many bills of each denomination does the teller have?

-
Let, the number of $5,$10 & $20 are x,y& z respectively.
Now we can write from the above statement

5x+10y+20z = 370---------(1)
x+y+z= 35------------(2)
10y+20z= 7+5x
>-5x+10y+20z=7----------(3)

solving the above equations we get
x=36,3
y=-21.45
z=20.15 ! !

May be the above statement contains error data that's why we didn't get be getter result !

write it in number form

5x+10y+20z = 370
x+y+z= 35
10y+20z= 7+5x

solve the system for x,y and z
