The same question got answered here as well:

A sponge? 🤔🤔

That happened to me a few times and I think it's because the post got taken down. 

No answerer is paid on here, they are just kind people willing to help out others. 
 

I don't think it is possible to delete a question after it has been posted, however, I'm pretty sure you can always come back to edit it.

Let's suppose the number of large candies sold is x, and the number of small candies sold is y. 
 

Here are your two equations: 

x + y = 28

4y + 6x = 144

From the first equation, we get:

x = 28 - y

Plugging that into the second equation, we get:

4y + 6 ( 28 - y ) = 144

All you have to do next is expand 6 ( 28 - y ) , add them ( the two y expressions ) together, and then divide by the constant of y on both sides to get y ( the number of small candies sold )

To get x ( the number of large candies sold ), just plug y into the equation x + y = 28 and isolate the x ( you can do that by subtracting the value of y on both sides ).

I hope this helped! If I made a mistake somewhere please lmk .

You could try using a Venn diagram, maybe that'll help. 

Thanks! : D

Let's say x is the number of fancy shirts Kim bought, and y is the number of plain shirts she bought. 

27x + 13y = 214

x + y = 10

This means that x = 10 - y. We can plug 10 - y into the equation 27x + 13y = 214. This gives us 27 ( 10 - y ) + 13y = 214.

Expand: 270 - 27y + 13y = 214. Isolate the variable: 27y - 13 y = 270 - 214. Simplify and divide: y = 4. 

To get x, simply minus y (which is 4) from 10. 

Now we know that the number of plain shirts Kim bought is 4, and the number of fancy shirts Kim bought is 6.

Please correct me if I'm wrong! <3
