Answer:
x= 4, y=3
Step-by-step explanation:
2x + 3y = 17
3x - 2y = 6
----------
<u>If we double the first and triple the second equation, and add up, we can get rid of y:</u>
- 4x+6y= 34
- +
- 9x - 6y= 18
- -----------------
- 13x= 52
- x= 4
<u>Then it is easy to find the value of y:</u>
<u>Answer is</u>: x= 4, y=3
Answer:
The interest rate was of 0.1173 = 11.73%.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:

In this problem, we have that:

So



So



The interest rate was of 0.1173 = 11.73%.
