Answer:
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
x+12=23*2x+12=23∗2
we can divide both sides by 23
\frac{x+12}{23} =2
23
x+12
=2
so, the equation is :
\frac{x+12}{23} =2
23
x+12
=2
now, we can solve for x
Subtract both sides by 12
x+12-12=46-12x+12−12=46−12
x=34x=34
so,
the additional number of cookies is 34.......... it
