Question

If x= -2 and y=8 than how do you solve this problem in its simplest form. 4x=y/xy-4y=

Answer 1

4(-2)=8/-2(8)-4(8)

-8=-4(8)-32

-8=32-32

-8=0

Answer 2

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! :)
