Answer:
Hey There the Answer to this is x = nickels
y= dimes
x + y = 34
.05x + .10y= $1.90
-.10x - .10y = -3.40
-.05x + .10y = 1.90
-.05x = -1.50
x = 30 nickels
30 + y = 34
y = 4 dimes
(3,4) And that you get the answer.

Answer:
20 and 50
Step-by-step explanation:
x + y = 70
y = 2x + 10
Use the substitution method:
y = 70 - x
y = 2x + 10
70 - x = 2x + 10
3x = 60
x = 20
x + y = 70
20 + y = 70
y = 50
<u>x = 20</u>
<u>y = 50</u>
