You are baking cookies for your class. there are 23 total students in your class and you have baked 12 cookies. write and solve an equation to find the additional number x of cookies you need to bake in order to have 2 cookies for each student. write your equation so that the units on each side of the equation are cookies per student.
equation: =2
number of cookies: x= 34

we are given

total number of students =23

the additional number of cookies =x

you have baked 12 cookies

so, total number of cookies =x+12

the additional number x of cookies you need to bake in order to have 2 cookies for each student

so, we can find total number of cookies

total number of cookies = ( total number of students)*(cookies each student)

so, we can plug values

total number of cookies = ( 23)*(2)

total number of cookies = 23*2

so, we can set them equal

we can divide both sides by 23

so, the equation is :

now, we can solve for x

Subtract both sides by 12

so,

the additional number of cookies  is 34..........Answer

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
