donuts and cream puffs were 45 & 4 respectively !
<u>Step-by-step explanation:</u>
Here we have , twice the number of donuts was only 6 less than 24 times the number of cream puffs. 10 times the number of cream puffs was only 5 less than the number of donuts We need to find how many donuts and cream puffs were there . Let's find out:
Let number of donuts and cream puffs are x & y respectively ! So ,
- twice the number of donuts was only 6 less than 24 times the number of cream puffs
According to this statement equation is :
⇒ ![2x=24y-6](https://tex.z-dn.net/?f=2x%3D24y-6)
⇒
................(1)
- 10 times the number of cream puffs was only 5 less than the number of donuts
According to this statement equation is :
⇒ ![10y= x-5](https://tex.z-dn.net/?f=10y%3D%20x-5)
⇒
................(2)
Equation (1) & (2) :
⇒ ![12y-3=10y+5](https://tex.z-dn.net/?f=12y-3%3D10y%2B5)
⇒ ![2y=8](https://tex.z-dn.net/?f=2y%3D8)
⇒ ![y=4](https://tex.z-dn.net/?f=y%3D4)
Putting
in
:
⇒ ![x = 12(4)-3](https://tex.z-dn.net/?f=x%20%3D%2012%284%29-3)
⇒ ![x = 45](https://tex.z-dn.net/?f=x%20%3D%2045)
Therefore , donuts and cream puffs were 45 & 4 respectively !
I’m assuming you want to work out the area
area = length x width
area = 10 x 8
area = 80 inches^2

Solving for variables in equations is important for many reasons. Of course, it's important to be able to solve for them so you can pass math tests. But even more so, it's important for real-life applications. There are many uses for solving equations. They can provide answers for mathematicians, accountants, insurance companies- you name it! There are way too many to list! It may not seem important now, but just keep working at it! I personally think solving equations is a ton of fun!
