Answer:

(\frac{11}{5},12)

Step-by-step explanation:

The system is

5x-y=-1

-5x+3y=25

We the two equations to get:

5x+-5x+-y+3y=25+-1

We simplify t get

2y=24

We divide both sides by 2 to get:

y=12

We now substitute y=12 in to the top equation to get:

5x-12=-1

5x=11

x=\frac{11}{5}

162.5  is the simple interest for one year.

What does the term "simple interest" mean?

The principal of a loan or the initial deposit into a savings account serves as the foundation for simple interest.

                   Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.

P = $812.50

T = 1 Year

S.I. = ?

R = 20

According to question,

                 S.I. = P * R* T/100

                     = 812.50 * 20 * 1/100

                     = 16250/100

                    = 162.5
