k in (-oo:+oo)
(6*k)/5-(4*((3*k)/5+4/3)) = (4*k)/5-3/4 // - (4*k)/5-3/4
(6*k)/5-(4*((3*k)/5+4/3))-((4*k)/5)-(-3/4) = 0
(6*k)/5-4*((3*k)/5+4/3)+(-4/5)*k+3/4 = 0
(6*k)/5-4*(3/5*k+4/3)+(-4*k)/5+3/4 = 0
(-4*4*5*(3/5*k+4/3))/(4*5)+(4*6*k)/(4*5)+(-4*4*k)/(4*5)+(3*5)/(4*5) = 0
4*6*k-4*4*5*(3/5*k+4/3)-4*4*k+3*5 = 0
15-24*k-16*k-320/3 = 0
15-40*k-320/3 = 0
-40*k-275/3 = 0
(-40*k-275/3)/(4*5) = 0
(-40*k-275/3)/(4*5) = 0 // * 4*5
-40*k-275/3 = 0
-40*k-275/3 = 0 // + 275/3
-40*k = 275/3 // : -40
k = 275/3/(-40)
k = -55/24
k = -55/24
