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

[tex]x+12=23*2[/tex]

we can divide both sides by 23

[tex]\frac{x+12}{23} =2[/tex]

so, the equation is :

[tex]\frac{x+12}{23} =2[/tex]

now, we can solve for x

Subtract both sides by 12

[tex]x+12-12=46-12[/tex]

[tex]x=34[/tex]

so,

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