Answer:
x+4y=-35
-8x-4y=28
Step-by-step explanation:
The answer to the original equations is (1, -9). You can solve that by using substitution by moving the 4y over and substituting that equation for x on the second part of the top equation. Using elimination, the second set of answers will give you the same, (1, -9)!

Answer:
The amount at the end of second quarter is $1842.704
Step-by-step explanation:
Given as :
The principal in saving account = $1640
The rate of interest = 6 % compounded quarterly
The time period = 6 months
Now,<u> from compounded method</u>
The amount at the end of first quarter =
= principal + 6 % of principal
I.e
= $1640 + 6 % × $1640
Or,
= $1640 + $ 98.4
∴
= $1738.4
Again ,
The amount at the end of second quarter =
=
+ 6 % of
I.e
= $1738.4 + 6 % × $1738.4
Or,
= $1738.4 + $104.304
∴
= $1842.704
So, The amount at the end of second quarter =
= $1842.704
Hence , The amount at the end of second quarter is $1842.704 Answer
