Question 1134552
x of the five dollar bills
y of the ten-dollar bills
{{{system(x+y=15,5x+10y=100)}}}---------first equation is for coin counts and second equation is for amount of money in dollars.


Simplify the money equation.
{{{x+2y=20}}}


System of Equations should be:
{{{system(x+y=15,x+2y=20)}}}



Use Elimination for part of the solution.
Subtract first equation from second equation.....
{{{highlight_green(y=5)}}}------------the ten-dollar bills

therefore {{{highlight_green(x=10)}}}---------the five-dollar bills
