There are 32 students in Jenna's class. Jenna brought in 13 cupcakes. Which
equation can be used to find the number
of cupcakes the class still needs (n) so that
everyone will get one?

Of the 27 students in class, only 12 have cupcakes, so to determine the amount of students who still need cupcakes, we subtract the number of those who have them, so the equation should look like

27 - 12 = n

n = 15

Step-by-step explanation:

You  can either use 13 + n= 32 or 32 - n= 13

Step-by-step explanation:

I hope this helped!!

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
