Solution for 1/2(2n+5)=5n-12-n equation: 


n in (-oo:+oo)

(1/2)*(2*n+5) = 5*n-n-12 // - 5*n-n-12

(1/2)*(2*n+5)-(5*n)+n+12 = 0

(1/2)*(2*n+5)-5*n+n+12 = 0

1/2*(2*n+5)-5*n+n+12 = 0

1/2*(2*n+5)-5*n+n+12 = 0

n-4*n+5/2+12 = 0

5/2-3*n+12 = 0

29/2-3*n = 0

29/2-3*n = 0

29/2-3*n = 0 // - 29/2

-3*n = -29/2 // : -3

n = -29/2/(-3)

n = 29/6

n = 29/6
