Solution for 7d-1/2(2d-8)=-5/4(d+8) equation: 


d in (-oo:+oo)

7*d-((1/2)*(2*d-8)) = (-5/4)*(d+8) // - (-5/4)*(d+8)

7*d-((1/2)*(2*d-8))-((-5/4)*(d+8)) = 0

(-1/2)*(2*d-8)+(5/4)*(d+8)+7*d = 0

5/4*(d+8)-1/2*(2*d-8)+7*d = 0

5/4*(d+8)-1/2*(2*d-8)+7*d = 0

1/4*d+7*d+14 = 0

29/4*d+14 = 0

29/4*d+14 = 0

29/4*d+14 = 0 // - 14

29/4*d = -14 // : 29/4

d = -14/29/4

d = -56/29

d = -56/29
