Lyric Cross · Answer 1

The number of nickels is 8+2q (q being quarters). so if 8+2q=42, subtract 8 from both sides. That gives you 2q=34. Now, divide both sides by 2. q=17. 17 quarters

Rocco Anthony · Answer 2

17, because if there are 8 more than twice the number of quarters than nickels, and there are 42 nickles, and you need to find quarters, then you do the opposite equation. so instead of 8 + x*2+=42 (x representing the number we do not know), you do 42-8/2. So 42-8 = 34, and 34/2 = 17.
