Solution for 5=(7-x)/(1+x) equation: 


D( x )

x+1 = 0

x+1 = 0

x+1 = 0

x+1 = 0 // - 1

x = -1

x in (-oo:-1) U (-1:+oo)

5 = (7-x)/(x+1) // - (7-x)/(x+1)

5-((7-x)/(x+1)) = 0

(-1*(7-x))/(x+1)+5 = 0

(-1*(7-x))/(x+1)+(5*(x+1))/(x+1) = 0

5*(x+1)-1*(7-x) = 0

6*x-2 = 0

(6*x-2)/(x+1) = 0

(6*x-2)/(x+1) = 0 // * x+1

6*x-2 = 0

6*x-2 = 0 // + 2

6*x = 2 // : 6

x = 2/6

x = 1/3

x = 1/3
