Lizzy: Steve is holding nickels and dimes in his hand. He has 4 more dimes than nickels. He has a total of 70 cents in his hand. How many nickels is he holding?.
Me: Hmmm, let me think. I think this is the detailed solution:

Let x be the number of nickels he is holding. His nickels are worth 5 * x = 5x cents. He has x + 4 dimes. The dimes are worth 10 * (x + 4). The total worth of the nickels and dimes is 5x + 10 * (x + 4) = 70. 5x + 10x + 40 = 70. 15x = 30. x = 2, Steve has 2 nickels in his hand. Final answer: 2.
