Solution for (c+11)/3c=4 equation: 


c in (-oo:+oo)

c*((c+11)/3) = 4 // - 4

c*((c+11)/3)-4 = 0

(c*(c+11))/3-4 = 0

(c*(c+11))/3+(-4*3)/3 = 0

c*(c+11)-4*3 = 0

c^2+11*c-12 = 0

c^2+11*c-12 = 0

c^2+11*c-12 = 0

DELTA = 11^2-(-12*1*4)

DELTA = 169

DELTA > 0

c = (169^(1/2)-11)/(1*2) or c = (-169^(1/2)-11)/(1*2)

c = 1 or c = -12

(c+12)*(c-1) = 0

((c+12)*(c-1))/3 = 0

((c+12)*(c-1))/3 = 0 // * 3

(c+12)*(c-1) = 0

( c+12 )

c+12 = 0 // - 12

c = -12

( c-1 )

c-1 = 0 // + 1

c = 1

c in { -12, 1 }
