hey u can apply simle cross multiplications as follows:
your question is:
5 = 7_
X-6 1
5 = 7_
X-6 1
This results in :
5*1 = 7*(X-6)
5 = 7X -42
7X = 42+5
7X = 47
X = 47/7

5/(x-6)=7 multiply both sides by x-6
5=7(x-6)=7x-42 add 42 to each side
47=7x divide by 7
x=47/7

multiply both sides by x
5(x/x) - 6x = 7x
subtract 6x from both sides to get axx x's on one side
5 = 7x + 6x, (x/x = 1)
factor:
5 = x(7+6)
divide both sides by 13 (=7+6) and swap sides for convention:
x = 5/13

5/x-6=7
5/x=7+6
5/x=13
5/x over 1/x=13 over 1/x
5/x(x/1)=13(x/1)
5=13x
5/13=x
my answer is 5/13

as i understand this question, 5/(x-6)=7,
then 5=7(x-6)
5=7x-42
5+42=7x
7x=47
x=47/7
x=6.72

5/[x-6]=7
7[x-6]=5
7x=5+42
x=47/7
=6+5/7
=6.71

if it is 5 : ( x - 6 )= 7 then------- x= +7
if it is (5 : x) - 6 = 7 then--------- x= +5/13
that's right!
