Answer 1

let x = number of 1$ bills
let y = number of 5$ bills

x+y=12
1*x+5*y=16

solve for y?

Answer 2

$16 in $1 bills and $5 bills."
x = number of one-dollar bills
y = number of five-dollar bills

1x + 5y = 16

"he received a total of 12 bills"
x + y = 12
x = 12 - y

1(12-y) + 5y = 16
12 - y + 5y = 16
4y = 4
y = 1
x = 12 - y = 11
