Question

Please help in solving : (2x+10)/((x)*(x+10))= 1/12 , find x

Answer 1

12(2x+10)=x^2+10x
x^2-14x-120=0
(x-20)(x+6)=0
x=20.-6

Answer 2

any simpler way to solve it

Answer 3

(2x+10)/(x(x+10))=1/12
(x+x+10)/(x(x+10))=1/12
1/(x+10)+1/x =1/12=1/20+1/30
this gives u x=20;
and if u write 1/12=1/4-1/6 =1/(-6+10)+1/(-6)
this gives u x=-6

Answer 4

cold you please let me know how you got: 1/(x+10)+1/x =1/12=1/20+1/30

Answer 5

1/30+1/20=(3+2)/60=5/60=1/12

Answer 6

the best way to solve this is using factorization which i did first
