x in (-oo:+oo)
-x/50 = (6-x)/20 // - (6-x)/20
-((6-x)/20)-x/50 = 0
(-1*(6-x))/20-x/50 = 0
(-1*50*(6-x))/(20*50)+(20*(-x))/(20*50) = 0
20*(-x)-1*50*(6-x) = 0
30*x-300 = 0
(30*x-300)/(20*50) = 0
(30*x-300)/(20*50) = 0 // * 20*50
30*x-300 = 0
30*x-300 = 0 // + 300
30*x = 300 // : 30
x = 300/30
x = 10
x = 10
