Solve the system. x−5y=5 2x−9y=7

Answers

Answer 1

Answer:

x = 10 | y = -3

Explanation:

2x−9y=7

x−5y=5

Solve by elimination

2x−9y=7

2x−10y=10

y = -3

x-5(-3) = 5

x = 10

Answer 2
Answer: x= -10 ; y= -3

Explain: set x= 5 + 5y
=> 2x - 9y =7
<=> 2.(5+5y) -9y= 7
<=> 10 + 10y - 9y= 7
<=> y= -3

Replace y= -3 => x= 5+5y
<=> x= -10

To test you can replace x,y in the original system.‍♀️

For the valuation of bonds that make semiannual payments, the number of periods doubles, whereas the amount of cash flow decreases by half. Using the values of cash flows and number of periods, the valuation model is adjusted accordingly.
