3D + 4d + dD + -1d2 = -6 + 9d

Solving for variable 'D'.

Move all terms containing D to the left, all other terms to the right.

Add '-4d' to each side of the equation.
3D + 4d + dD + -4d + -1d2 = -6 + 9d + -4d

Reorder the terms:
3D + 4d + -4d + dD + -1d2 = -6 + 9d + -4d

Combine like terms: 4d + -4d = 0
3D + 0 + dD + -1d2 = -6 + 9d + -4d
3D + dD + -1d2 = -6 + 9d + -4d

Combine like terms: 9d + -4d = 5d
3D + dD + -1d2 = -6 + 5d

Add 'd2' to each side of the equation.
3D + dD + -1d2 + d2 = -6 + 5d + d2

Combine like terms: -1d2 + d2 = 0
3D + dD + 0 = -6 + 5d + d2
3D + dD = -6 + 5d + d2

Reorder the terms:
6 + 3D + -5d + dD + -1d2 = -6 + 5d + d2 + 6 + -5d + -1d2
