Answer 1

x-4          4x-44       16-x

------- + ---------- = ----------  

6            x-6             2

(x-4)*(x-6)    (4x-44)*6    16-x
-----------  + -----------=-------
6(x-6)            6(x-6)      2

x2-6x-4-10        24x-264       16-x
------------- + ------------= ----------
6(x-6)          6(x-6)           2


x2-18x-287       16-x
------------ = -----------
6(x-6)           2




2 x2-36x-574=(6x-36)(16-x)

2 x2-36x-574=96x-6 x2-576+36x
8 x2+2=0/-2
8 x2=-2/8
x2=-1/4
x=-1/2
