-6y + 11x = -36....multiply by 4
-4y + 7x = -24....multiply by -6
-----------------
-24y + 44x = - 144 (result of multiplying by 4)
24y - 42x = 144 (result of multiplying by -6)
----------------add
2x = 0
x = 0
-4y + 7x = -24
-4y + 7(0) = -24
-4y = -24
y = -24/-4
y = 6
solution is (0,6)
The wavelength of the sound wave if the frequency is increased to the given value is 0.44m.
Given the data in the question;
- Frequency of sound wave a;
- Wavelength of sound wave a;
Speed of sound wave; 
- Frequency of sound wave b;
Wavelength of sound wave b; 
<h3>Wavelength</h3>
Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.
It is expressed as;
Where v is velocity and f is frequency.
First, we calculate the velocity of the sound wave in air from sound wave a.
Now, we determine the wavelength of sound wave b using the velocity of sound wave in air calculated above.
Therefore, the wavelength of the sound wave if the frequency is increased to the given value is 0.44m.

Answer:
54 dollars
Explanation:
Because this problem involves simple interest, and the money is only deposited for one year, you can calculate the amount of money in the bank after one year by thinking about a percent increase. Johnny starts with 50 dollars in his bank account, and we are given that he will experience an 8% increase over the year. This means that the amount of money in his bank account after one year is just 50 + 0.08*50 (the principal amount plus the simple interest, or amount of money that increases during the year). This is equal to 50 + 4, or 54 dollars.
Note that, whenever we are dealing with simple interest, the amount of money in the bank after a certain number of years is just P(1 + PRT), where P is the principal amount, R is the interest rate, and T is the number of years the money is in the bank.

<h2>
What is a mortgage loan?</h2>
A mortgage loan can be defined as a secured loan that is typically used to finance (purchase) or maintain a property in real estate such as a land, home, etc.
<h3>
The feature of a mortgage loan.</h3>
Basically, a mortgage loan is usually provided to a borrower by a mortgage lender or a financial institution (bank) while an immovable asset (collateral) is promised by the borrower to the mortgage lender in the event that payments are stopped.
During the application of a mortgage loan, the borrower uses his or her home as a collateral. Thus, these two (2) information are essential for completing an initial mortgage loan application:
- Current debts and credit history.
