Sara is having a dinner party for four friends and needs to reduce the serving size of the meatloaf recipe. she uses the equation x/4=5 how many servings did the recipe originally make?

To solve this equation you need to find the value of x.
You can do this by using inverse operations.
and getting x alone.
 x/4=5
the opposite of division is multiplication so we multiply 5 by 4
x=5*4
we now have x alone and must solve the rest of the equation
5*4=20
There for x=20
The recipe originally made 20 servings.

I hope this helped:) If you have any questions pleas comment and i will do my best to answer and/ or explain :)
