at davenport house of pizza the total price for 6 large pizzas plus 2 medium pizzas is 86 dollars. the total for 4 large pizzas and 3 medium pizzas is 72.75 dollars what is the price of the medium pizza

Step-by-step explanation:

L = large pizzas

M=medium pizzas

6L+2M=86

4L+3M=72.75

6L+2M-2M=86 + (-2M)

6L divide by 6 to single out L=-2M+86 divide by 6

L=-1/3M + 43/3

4 (-1/3M+43/3) + 3M=72.75

5/3M+172/3=72.75

5/3M+172/3 - 172/3=72.75 + (-172/3)

5/3M divide by 5/3M=15.416667 divide by 5/3M

M=9.25
