5÷x-4 - 2÷x+2 = 4÷x-4
Alborosie
I'd suggest you begin by subtracting 4 / (x-4) from both sides.  Doing that would leave you with    1 / (x-4)   -     2 / (x+2) =  0.

LCD is (x-4)(x+2).  Mult. all three terms by (x-4)(x+2).  The resulting equation is 

x+2 - 2(x-4) = 0.     Then x+2 = 2x - 8  =>  x = 10

Subst. 10 for x in the original equation to verify that 10 is indeed a solution.

HELP PLEASEEEE!!!!!! Last one :(
crimeas [40]

Answer:

4

Step-by-step explanation:

RS + ST = RT

=> 3x-8 + x = 2x

4x - 8 = 2x

Subtract 2x from both the sides,

4x - 2x - 8 = 0

2x - 8 = 0

Add 8,

2x = 8

Divide by 2,

x = 8/2 = 4

Length of line segment ST = x = 4
