A=#nickels, b=#quarters
5a + 25b = 410 total value
5(a + 5b) = 410
a + 5b = 82
a + b = 30 total no. of coins
subtracting . . . 4b = 52
thus b = 13 and a = 17
13 quarters and 17 nickels = 13*25 + 17*5 = 410 = $4.10
5x+17=-23
Subtract 17 on both sides
5x=-40
Divide by 5 on both sides
X=-8
Double Check:
5(-8)+17=-23
-40+17=-23
-23=-23
Order of operations so -6 × -5 = 30
-6 + 30 = 24 is the answer
Hope this helps!
