xy2 + x2y + x3 + y3 = 0

Solving
xy2 + x2y + x3 + y3 = 0

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

Add '-1xy2' to each side of the equation.
xy2 + x2y + x3 + -1xy2 + y3 = 0 + -1xy2

Reorder the terms:
xy2 + -1xy2 + x2y + x3 + y3 = 0 + -1xy2

Combine like terms: xy2 + -1xy2 = 0
0 + x2y + x3 + y3 = 0 + -1xy2
x2y + x3 + y3 = 0 + -1xy2
Remove the zero:
x2y + x3 + y3 = -1xy2

Add '-1x2y' to each side of the equation.
x2y + x3 + -1x2y + y3 = -1xy2 + -1x2y

Reorder the terms:
x2y + -1x2y + x3 + y3 = -1xy2 + -1x2y

Combine like terms: x2y + -1x2y = 0
0 + x3 + y3 = -1xy2 + -1x2y
x3 + y3 = -1xy2 + -1x2y

Add '-1x3' to each side of the equation.
x3 + -1x3 + y3 = -1xy2 + -1x2y + -1x3

Combine like terms: x3 + -1x3 = 0
0 + y3 = -1xy2 + -1x2y + -1x3
y3 = -1xy2 + -1x2y + -1x3

Add '-1y3' to each side of the equation.
y3 + -1y3 = -1xy2 + -1x2y + -1x3 + -1y3

Combine like terms: y3 + -1y3 = 0
0 = -1xy2 + -1x2y + -1x3 + -1y3

Simplifying
0 = -1xy2 + -1x2y + -1x3 + -1y3
