You are baking brownies for your class. There are 28 total students in your class and you have baked 23 brownies. Write and solve an equation to find the additional number x of brownies you need to bake in order to have 2 brownies for each student. Write your equation so that the units on each side of the equation are brownies per student.

2(28)=23+x

Step-by-step explanation:

There are 28 students and each student needs two brownies. You have to multiply 28 by 2 so you will have to total number on one side.

On the other you need to have the number of brownies you have at the moment and x for the number you need to bake. You want to add them because you will need to put those numbers together to get the number on the opposite side.

28x2=56 so 56=23+x. Subtract the 23 from both sides to get 33=x. x=33

To check plug 33 into x to get 2(28)=23+33. 56=23+33. 56=56

you need 33 more brownies.

So the equation would be 2(28)=23+x.
