Answer:
20 dimes and 10 nickels
Step-by-step explanation:
There’s 20 dimes 20x.10= 2.00 that leaves 10 nickels 10x.05=.50 2.00+.50=2.50
x/2 + x = 30 -> $2.50
20/2 + 20 = 30
X = 20, therefore:
dimes = 20
nickels = 10
Put x = 7 and y = 6 to the equations:
-2x + y = 20
L = -2(7) + 6 = -14 + 6 = -7
R = 20
L ≠ R
