Mathematics

Answer:

Step-by-step explanation:

The easiest way to do this is to solve for x first, then y.

Plug the second equation (y = 2x - 5) into the first equation (-3x - 4y = -2).  This will give you -3x - 4(2x - 5) = -2.  Solve for x.

-3x - 4(2x - 5) = -2

-3x - 8x + 20 = -2

-11x = -22

x = 2

Now, you can plug in the x-value into the second equation.

y = 2(2) - 5

y = 4 - 5

y = -1

jenny wants to buy a winter coat for $200. the store advertises that customers can take 25% off the original price and then take
777dan777 [17]
Hello!

Let's check:

200 * 25% = 50

200 - 50 = 150

150 * 10% = 15

150 - 15 = 135

So, with the 25% and then an extra 10% off, the coat would cost $135.

200 * 35% = 70

200 - 70 = 130

So, Jenny's friend is incorrect, because that is not the same as a 35% discount.
