Question 1134552: You have 15 bills in your pocket you only have five dollar and $10 bills the combined value of the bills is $100 write and solve a system of equations to represent the scenario.I tried doing it in the form of Y=mx+b and then I isolated the y’s in the x’s and then when that still didn’t help me I tried to plug in 15 for Y and X in both equations and honestly I confused myself more

You can put this solution on YOUR website!
x of the five dollar bills
y of the ten-dollar bills
system%28x%2By=15%2C5x%2B10y=100%29---------first equation is for coin counts and second equation is for amount of money in dollars.

Simplify the money equation.
x%2B2y=20

System of Equations should be:
system%28x%2By=15%2Cx%2B2y=20%29


Use Elimination for part of the solution.
Subtract first equation from second equation.....
highlight_green%28y=5%29------------the ten-dollar bills
therefore highlight_green%28x=10%29---------the five-dollar bills
