let one number be x
other will be 30-x
..
5x=2(30-x)+17
5x=60-2x+17
5x+2x=60+17
7x=77
/7
x= 11
other number = 19
and A collection of nickels and quarters totals 3.40. the totale number of coins is 24. how many of each are there?
total coins = 24
let x be nickels
24-x will be quarters
..
value 340 cents
..
5x+25(24-x)=340
5x+600-25x=340
-20x=340-600
-20x=-260
x=13 nickels
quarters = 11
...
11*25+5*13=340
