Hi there!

So we know that:

x = -2

y = 8

And we have this equation to solve : 4x = \frac{y}{xy - 4y}


To solve the equation, you need to replace the letters "x" and "y" in the equation with their value :


4 x -2 = \frac{8}{(-2x8) - (4x8)}


Now all you need to do is calculate everything:


4 × -2 = -8

-2 × 8 = -16

4 × 8 = 32


-8 = \frac{8}{-16 - 32}


-16 + -32 = -48


-8 = \frac{8}{-48}


\frac{8}{-48}  \left \{ {{divided by 8 = 1} \atop {divided by 8 = -6}} \right. = \frac{1}{-6}


-8 = -\frac{1}{6}


I'm not sure if this would be the simplest form you are looking for..


If there's anything, just let me know! :)

Hi there!

\large\boxed{0, -\frac{9}{4}  }

2x - 4y = 9

Begin by isolating the y variable by moving 2x to the right-hand side of the equation. (Subtract 2x from both sides):

2x - 2x - 4y = 9 - 2x

-4y = 9 - 2x

Further isolate by dividing both sides by -4:

-4y / (-4) = (9 - 2x) / (-4)

y = -9/4 - 2x/(-4)

Simplify further:

y = -9/4 + 1/2x

y = 1/2x - 9/4

The "b" value is the y-intercept, therefore:

x = 0 at y = -9/4

Show and explain how replacing one equation by the sum of that equation and a multiple of the other produces a system with the s
My name is Ann [436]
First, let's multiply the first equation by two on the both sides:
<span>8x + 7y = 39         /2
</span>⇒ 16x + 14y = 78

Now, the system is:
<span>16x + 14y = 78
</span><span>4x – 14y = –68
</span>
After adding this up in the column:
(16x + 4x) + (14y - 14y) = 78 - 68
20x = 10
⇒ x = 10/20 = 1/2


y can be calculated by replacin the x:
<span>8x + 7y = 39
</span>⇒ 8 · 1/2 + 7y = 39
4 + 7y = 39
7y = 39 - 4
7y = 35
⇒ y = 35 ÷ 7 = 5
