Question

Mary ate one of the muffins she baked and had 12 left. Write an equation to find how many muffins Mary started with.

Answer 1

Well, do you know what 12+1 is? Because if she ended with 12 and ate 1 to begin with, you just add those numbers together, and that is your answer!

Answer 2

x - 1 = 12

Explanation:

Given: Mary ate one of the muffins she baked and had 12 left.

Let "x" be the number muffins she baked. She ate one and left with 12.

x - 1 = 12

So the required equation is x -1 = 12 to find the number muffins Mary started with.
