Question

Alison baked y cake. She gave foure to Megan and one to Nabil. How many cakes does she have left?

Answer 1

Okay, she has 'y' amount of cakes. She gives four away to Megan and one away to Nabil, we can subtract these from 'y':

$\sf y-5-1$

Simplify:

$\sf y-6$

So she has y - 6 cakes left.
