Solving for variable 'd'.

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

Add 'su' to each side of the equation.
-7dx + 3dxy + -4dx2 + -1su + su + -1sux = 0 + su

Combine like terms: -1su + su = 0
-7dx + 3dxy + -4dx2 + 0 + -1sux = 0 + su
-7dx + 3dxy + -4dx2 + -1sux = 0 + su
Remove the zero:
-7dx + 3dxy + -4dx2 + -1sux = su

Add 'sux' to each side of the equation.
-7dx + 3dxy + -4dx2 + -1sux + sux = su + sux

Combine like terms: -1sux + sux = 0
-7dx + 3dxy + -4dx2 + 0 = su + sux
-7dx + 3dxy + -4dx2 = su + sux

Reorder the terms:
-7dx + 3dxy + -4dx2 + -1su + -1sux = su + -1su + sux + -1sux

Combine like terms: su + -1su = 0
-7dx + 3dxy + -4dx2 + -1su + -1sux = 0 + sux + -1sux
-7dx + 3dxy + -4dx2 + -1su + -1sux = sux + -1sux

Combine like terms: sux + -1sux = 0
-7dx + 3dxy + -4dx2 + -1su + -1sux = 0
