Answer:

x=4                         x=-2

Step-by-step explanation:

x+4                  x

----------- = ------------

4                  x-2

Using cross products

(x+4)(x-2) = 4x

FOIL

x^2 -2x +4x -8 = 4x

Combine like terms

x^2 +2x -8 = 4x

Subtract 4x from each side

x^2 +2x-4x -8 = 4x-4x

x^2 -2x-8 =0

Factor

What 2 numbers multiply to -8 and add to -2

-4*2 =-8

-4+2 = -2

(x-4) (x+2) =0

Using the zero product property

x-4+4 =0+4         x+2-2=0-2

x=4                         x=-2

How do you solve 6(2/3x-3)&gt;3
VARVARA [1.3K]

Answer:

14>3

Step-by-step explanation:

you would need to turn the 3 in the parenthesis into a fraction which would result in 9/3. 2/3 - 9/3= -7/3      

Multiply the 7/3 by 6 and by what I have always been taught, you only multiply the top of the fraction. This would leave it to be 42/3 which would be known as 14.

So therefore the answer would be 14>3
