How do you solve 2 + 8 - z = -24 for z
Naily [24]

Answer:

z=34

Step-by-step explanation:

2 + 8 - z = -24

add

10-z = -24

subtract 10 from each side

10-z-10 = -24-10

-z = -34

multiply by -1

-1*-z = -34 * -1

z = 34

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.
