You have a coupon good for $6 off the price of any large pizza. you also get a 20% discount on any pizza if you show your student id. how much more would you pay for a large pizza if the cashier applies the coupon first? a. $1.20 b. $0.00 c. $1.50 d. $.50

x = -27

v = 12

n = -20

Step-by-step explanation:

1) -45 - x = - 18

- Add 45 to both sides

-45 - x + 45 = -18 + 45

Group like terms:

-x + -45 + 45 = -18 + 45

Simplify the arithmetic:

-x = -18 + 45

Simplify the arithmetic:

-x = 27

- Isolate the X

Multiply both sides by-1

-x · -1 = 27 · -1

Remove the one(s):

x= 27 · -1

Simplify the arithmetic:

x= -27

2) v - 55 = -43

1. Group all constants on the right side of the equation

v - 55 = -43

Add 55  to both sides:

v - 55 + 55 = -43 + 55

Simplify the arithmetic:

v = -43 + 55

Simplify the arithmetic:

v = 12

3)  -2 = n/10

1. Swap sides

-2 = n/10

Swap sides

n/10 = -2

2. Isolate the n

n/10 = -2

Multiply to both sides by 10:

n/10 * 10 = -2 * 10

Group like terms:

1/10 * 10n = -2 * 10

Simplify the fraction:

n = -2 * 10

Simplify the arithmetic:

n = -20
