Solution for 7/5=x/20-(5-x)/2 equation: 


x in (-oo:+oo)

7/5 = x/20-((5-x)/2) // - x/20-((5-x)/2)

(5-x)/2-(x/20)+7/5 = 0

(5-x)/2-x/20+7/5 = 0

(5*20*(5-x))/(2*5*20)+(2*5*(-x))/(2*5*20)+(2*7*20)/(2*5*20) = 0

5*20*(5-x)+2*5*(-x)+2*7*20 = 0

280-110*x+500 = 0

780-110*x = 0

(780-110*x)/(2*5*20) = 0

(780-110*x)/(2*5*20) = 0 // * 2*5*20

780-110*x = 0

780-110*x = 0 // - 780

-110*x = -780 // : -110

x = -780/(-110)

x = 78/11

x = 78/11
