Debra has a stack of nickels and dimes. The number of nickels is 10 more than twice
the number of dimes. The value of her stack of
coins is $6.50. Which system of equations can
be used to find the number of nickels, n, and
dimes, d, in Debra's stack of coins?
a
n - 2d + 10
.10n + .05d = 6.50
b
n = 20 + 10
.05n+.100 = 6.50
n-d + 10
.10n + .050 -6.50
d
d = 2n + 10
.05n +. 100 = 6.50

With this question! what is process of elimination? ? p.s. my brothers acc got banned so add his new one @ yamauchiyamyam17
