Solution for 2/5k-(k+1/2)=1/10(k+2) equation: 


k in (-oo:+oo)

(2/5)*k-k-(1/2) = (1/10)*(k+2) // - (1/10)*(k+2)

(2/5)*k-((1/10)*(k+2))-k-(1/2) = 0

(-1/10)*(k+2)+(2/5)*k-k-1/2 = 0

(2*k)/5-1/10*(k+2)-k-1/2 = 0

(-1/10*2*5*(k+2))/(2*5)+(2*2*k)/(2*5)+(2*5*(-k))/(2*5)+(-1*5)/(2*5) = 0

2*2*k-1/10*2*5*(k+2)+2*5*(-k)-1*5 = 0

3*k-10*k-5-2 = 0

-7*k-5-2 = 0

-7*k-7 = 0

(-7*k-7)/(2*5) = 0

(-7*k-7)/(2*5) = 0 // * 2*5

-7*k-7 = 0

-7*k-7 = 0 // + 7

-7*k = 7 // : -7

k = 7/(-7)

k = -1

k = -1
