Ben brought a total of 11 pizzas for his class party the amount of larage pizza was one less than twice the amount of medium . How many large and how many medium pizzas did he buy?

m=4 and L=7

Step-by-step explanation:

The problem above can be solved by using algebraic expressions. First, let's get the number of medium pizzas.

Let's solve.

m+L=11

L=2m-1

m+(2m-1)=11

m+2m-1=11

3m-1=11

3m=11+1

3m=12

m=

m=4

Ben bought 4 medium pizzas.

Next, let's get the number of large pizzas he bought.

L=2m-1

L=2(4)-1

L=8-1

L=7

Ben bought 7 large pizzas. This makes the third choice correct.

Let's check.

m+L=11

4+7=11 (correct)
