Question

You are baking cookies for your class. There are 23 students I your class and you have baked 12 cookies. Write and solve an equation to find the additional number of x 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 equations are cookies per student

Answer 1

(23 x 2) - 12 = x  

We need 2 cookies per student, so multiply the amount of students by 2. which is 23 x 2. Then because you already baked 12 subtract 12 from the original amount you needed to bake.  Which is 46 - 12. Oh and if you wanted the answer, it's 34.
