Solve by elimination 2x+5y=17 6x-5y=19

By elimination:

2x + 5y = 17

6x - 5y = 19

We can add the second equation to the first in order to isolate one variable.

(2x + 5y) + (6x - 5y)

8x = 17

Because we added the left side, we have to add the right side here as well.

17 + 19 = 36

8x = 36

Divide both sides by 8

x = 4.5

We can plug this value back into the original equation to find the value of y.

2(4.5) + 5y = 17

9 + 5y = 17

Subtract 9 from both sides.

5y = 8

Divide both sides by 5.

y = 1.6

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
