The cost of endless chicken wings at Restaurant X is $10. The cost of chicken wings at Restaurant Z is 50¢ per wing plus a $1.50 charge for sauce. The total cost, c, of n chicken wings at either
restaurant can be represented by an equation. Write and graph a system to find how many chicken
wings you have to have for the cost to be the same at both restaurants.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

there are infinitely many solutions.
