Solution for -5r/2-1/2(-4-3r)=10 equation: 


r in (-oo:+oo)

(-5*r)/2-((1/2)*(-(3*r)-4)) = 10 // - 10

(-5*r)/2-((1/2)*(-(3*r)-4))-10 = 0

(-1/2)*(-3*r-4)+(-5*r)/2-10 = 0

(-5*r)/2-1/2*(-3*r-4)-10 = 0

(-1/2*2*(-3*r-4))/2+(-5*r)/2+(-10*2)/2 = 0

-1/2*2*(-3*r-4)-5*r-10*2 = 0

4-2*r-20 = 0

-2*r-16 = 0

(-2*r-16)/2 = 0

(-2*r-16)/2 = 0 // * 2

-2*r-16 = 0
