Answer:

x=3,y=-10

Step-by-step explanation:

First, we add 21 to both sides of the first equation

13x=-21-6y

+21   +21

13x+21=-6y      Now divide by -1 to make it positive

/-1   /-1    /-1

-13x-21=6y

Now we have to subtract 36 on both sides of the second equation

-8x=36+6y

-36   -36

-8x-36=6y

Since both equations equal 6y we can solve the equation by making them "equal" each other

-13x-21=-8x-36         Add 36 to both sides

     +36      +36

-13x+15=-8x      Add 13x to both sides

+13x      +13x

15=5x            Divide by 5

/5  /5    

x=3

Now use the x value to solve

13(3)=-21-6y

39=-21-6y    Add 21 to both sides

+21   +21

60=-6y

/-6    /-6

y=-10

Hope this helped!

Let xy=3 and dy/dt=4. Find dx/dt when x=5
tino4ka555 [31]

Answer:

xy = 3

d/dt(xy) = d/dt(3)

ydx/dt + xdy/dt = 0

y = 3/x so substitute 3/5 for y, 5 for x, and 5 for dy/dt; and solve for dx/dt.

3/5(dx/dt) + 5(5) = 0

3/5(dx/dt) = -25

dx/dt = -125/3

Step-by-step explanation:

this should be able to help you :)
