Question 1202534
x = number of 1 dollar bills.
y = number of 5 dollar bills.
jar contains 34 bills
x + y = 34
total money in the jar is 110 dollars.
x + 5y = 110
solve for y in the first equqtion to get:
y = 34 - x
replace y in the second equation with tha to get:
x + 5 * (34 - x) = 110
simplify to get:
x + 170 - 5x = 110
combine like terms to get:
-4x + 170 = 110
add 4x to both sides of the equation and subtract 110 from both sides of the equation to get:
60 = 4x
solve for x to get:
x = 15
since x + y = 34, then y must be equal to  19.
x + y becomes 15 + 19 which is equal to 34.
x + 5y becomes 15 + 95 which is equal to 110.
values look good.
solution is he has 15 one dollar bills and 19 five dollars bills.
