x in (-oo:+oo)
(2*x+1)/5+(3-x)/2 = 7/10 // - 7/10
(2*x+1)/5+(3-x)/2-(7/10) = 0
(2*x+1)/5+(3-x)/2-7/10 = 0
(2*10*(2*x+1))/(2*5*10)+(5*10*(3-x))/(2*5*10)+(-7*2*5)/(2*5*10) = 0
2*10*(2*x+1)+5*10*(3-x)-7*2*5 = 0
170-10*x-70 = 0
100-10*x = 0
(100-10*x)/(2*5*10) = 0
(100-10*x)/(2*5*10) = 0 // * 2*5*10
100-10*x = 0
100-10*x = 0 // - 100
-10*x = -100 // : -10
x = -100/(-10)
x = 10
x = 10
