Respuesta :

Answer:

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
