Mariah gathered all her stuffed animals. She sold twelve of them at a garage sale. After the garage sale, she had seventeen stuffed animals left. How many stuffed animals did Mariah begin with? Let a represent the number of stuffed animals Mariah started with.

a plus twelve equals seventeen

twelve times a equals seventeen

a minus twelve equals seventeen

a divided by twelve equals seventeen
