Add '-1xy2' to each side of the equation.
xy2 + xy3 + x3 + -1xy2 + 4y = 0 + -1xy2

Reorder the terms:
xy2 + -1xy2 + xy3 + x3 + 4y = 0 + -1xy2

Combine like terms: xy2 + -1xy2 = 0
0 + xy3 + x3 + 4y = 0 + -1xy2
xy3 + x3 + 4y = 0 + -1xy2
Remove the zero:
xy3 + x3 + 4y = -1xy2

Add '-1xy3' to each side of the equation.
xy3 + x3 + -1xy3 + 4y = -1xy2 + -1xy3

Reorder the terms:
xy3 + -1xy3 + x3 + 4y = -1xy2 + -1xy3

Combine like terms: xy3 + -1xy3 = 0
0 + x3 + 4y = -1xy2 + -1xy3
x3 + 4y = -1xy2 + -1xy3

Add '-1x3' to each side of the equation.
x3 + -1x3 + 4y = -1xy2 + -1xy3 + -1x3

Combine like terms: x3 + -1x3 = 0
0 + 4y = -1xy2 + -1xy3 + -1x3
4y = -1xy2 + -1xy3 + -1x3

Add '-4y' to each side of the equation.
4y + -4y = -1xy2 + -1xy3 + -1x3 + -4y

Combine like terms: 4y + -4y = 0
0 = -1xy2 + -1xy3 + -1x3 + -4y

Simplifying
0 = -1xy2 + -1xy3 + -1x3 + -4y
