System of equations (yay) x=nickels y=dimes
1st x+y=70
2nd .5x+.10y=4.65
3rd Move decimal (multiply everything by 100) : 5x=10y=465
x+y=70
-x -x
y=70-x
(Substitute) 5x+10(70-x)= 465
(Distribute) 5x+700-10x=465
(Solve equation) -5x=-235 >>> x=47 >>>
Answer- 47 dimes and 23 nickels
Please let me know if I need to explain further (:
