Step-by-step explanation:

x = -3, y =4

so, first we combine the fitting terms, and then we use these values in the expression in place of the variables.

-12x + 5y + 18x - 3y + 6 = 6x + 2y + 6

6×-3 + 2×4 + 6 = -18 + 8 + 6 = -4

Answer: There are 12 bills for $20, 13 bills for $10 and 14 bills for $5.

Step-by-step explanation:

Let the number of twenties be x

Let the number of tens be x+1

Let the number of fives be x+2

Amount from twenties will be given as

20\times x=20x

Amount from tens will be given as

10\times (x+1)=10x+10

Amount from fives will be given as

5\times (x+2)=5x+10

According to question,

20x+10x+10+5x+10=440\\\\35x+20=440\\\\35x=440-20\\\\35x=420\\\\x=\frac{420}{35}\\\\x=12

So, there are 12 bills for $20, 13 bills for $10 and 14 bills for $5.
