Answer:

Step-by-step explanation:

Remark

It's not 82.

You have to take the 62% off and then follow it with 20% from the new price.

Solution

62%

If you get a reduction of 62%, it means that you pay 100% - 62% = 38% of the marked price of $49.95.

38% price =49.95 * 62/100

38% price = 3096.9 / 100

38% price = $30.97

20%  Reduction

20% more means that you pay 100% - 20% = 80%

20% more reduction = 30.97 * 80/100

20% more reduction = 2478/100

20% more reduction = 24.78

Conclusion.

Your final price before taxes is $24.78

Answer:

x = -1, and y = -2, giving you the answer (-1, -2)

Step-by-step explanation:

In the second equation, we're told that y is equal to 2x.  With that, we can replace "y" in the first one with "2x", giving us:

-4x - 2x = 6

-6x = 6

x = -1

Now that we know the value of x, we can simply plug it into the first equation to find y:

-4x - y = 6

-4(-1) - y = 6

4 - y = 6

-4 + y = -6

y = -6 + 4

y = -2

So x = -1, and y = -2
