Let the $1 bills be x
Then $10 bills would be (60-x)
Total value is ....
1*x + 10(60-x)=x+600-10x=600-9x
but the total value is given and it is $240 so we have ....
600-9x = 240
add 9x on both sides
600-9x+9x=240+9x----->
600 = 240+9x
subtract 240 on both sides
600-240 = 240+9x-240
360 = 9x
divide both sides by 9
360/9 = 9x/9
40 = x
so the $1 bills are 40
and $10 bills are 60-40= 20

$ 1 bill x numbers
$10 bill 60-x numbers
Value of bills = $240
