X= 5y + 1
-2x + 9y = -1
-2(5y + 1) + 9y = -1
-10y - 2 + 9y = -1
-y - 2 = -1
-y = 1
y = -1
x + 5 = 1
x = -4

Answer:
158 quarters
54 dimes
Step-by-step explanation:
Let d = no. of dimes
q = no. of quarters
10d = value of all the dimes since each dime is worth 10 cents
and 25q = value of all the quarters since each quarter is worth 25 cents
$44.90 = 4490 cents
10d + 25q = 4490 d + q = 212
<u> - 10d - 10q = -2120</u>
15q = 2370
q = 158 quarters d + 158 = 212
d = 54 dimes
