Solution for (n-2)/(n+7)=4/3 equation:


D( n )

n+7 = 0

n+7 = 0

n+7 = 0

n+7 = 0 // - 7

n = -7

n in (-oo:-7) U (-7:+oo)

(n-2)/(n+7) = 4/3 // - 4/3

(n-2)/(n+7)-(4/3) = 0

(n-2)/(n+7)-4/3 = 0

(3*(n-2))/(3*(n+7))+(-4*(n+7))/(3*(n+7)) = 0

3*(n-2)-4*(n+7) = 0

-n-34 = 0

(-n-34)/(3*(n+7)) = 0

(-n-34)/(3*(n+7)) = 0 // * 3*(n+7)

-n-34 = 0

-n-34 = 0 // + 34

-n = 34 // * -1

n = -34

n = -34
