Step-by-step explanation:

44 = 12 + M

Step-by-step explanation:

Start with your final amount that everything else is going to equal

44 =

Then, add the $12 that is already saved to the other side\

44 = 12

But, that equation is not true yet, so we have to add the amount of money that she still needs to save

44 = 12 + M

That equation shows that the money she has saved ($12), plus the amount she still has to save will equal the amount she needs.
