Question

Sierra, An Eighth Grade Algebra Student

Answer 1

Hi Sierra--

 

You can always do a coin question:

 

Sierra has 9 coins. Some are dimes, some are nickels. Their total value is 65 cents. How many of each coin does she have?

 

So one equation will have to do with the NUMBER of those coins, and the other will be about the VALUE of the coins.

 

d + n = 9

 

10d + 5n = 65

 

Do you know how to solve these yet? Let me know!
