The value of the bills is $780. How many $5 bills are there?  Let x equal the number of $5 bills Let y equal the number of $20 bills We know that together the number of $5 bills and the $20 bills is 54, so that is the first equation. x + y = 54 Next the total value of the bills combined is $780, that is the second equation. 5x + 20y = 780  Now that we have our two equations we can solve by substitution. To do so we have to rearrange our first equation solving for one of the variables  x + y = 54 x        x y = 54 x  Next we will substitute this equation into the second, and solve.  5x + 20(54 x) = 780       (multiply 20 and 54, and multiply 20 and
x)  5x + 1080 â 20x = 780      (combine 5x and â 20x)  -15x + 1080 = 780        (subtract 1080 from both sides)   -15x = -300               (divide by -15)  x = 20   Now that we have our x value, we can solve for y using our first equation.  20 + y = 54   (subtract 20 from each side)  y = 34  Finally, to check the answers you substitute them into both of the equations.  20 + 34 = 54        54 = 54  TRUE  5(20) + 20(34) = 780       100 + 680 = 780                 780 = 780 TRUE  The final answer is there are 20 $5 bills, and 34 $20 bills. what will be a response to this person.
