Solution for 7/9=b/(b-10) equation: 


D( b )

b-10 = 0

b-10 = 0

b-10 = 0

b-10 = 0 // + 10

b = 10

b in (-oo:10) U (10:+oo)

7/9 = b/(b-10) // - b/(b-10)

7/9-(b/(b-10)) = 0

(-1*b)/(b-10)+7/9 = 0

(-1*9*b)/(9*(b-10))+(7*(b-10))/(9*(b-10)) = 0

7*(b-10)-1*9*b = 0

-2*b-70 = 0

(-2*b-70)/(9*(b-10)) = 0

(-2*b-70)/(9*(b-10)) = 0 // * 9*(b-10)

-2*b-70 = 0

-2*b-70 = 0 // + 70

-2*b = 70 // : -2

b = 70/(-2)

b = -35

b = -35
