Reorder the terms:
-1x2y + x2y + 2x3y + -4y = -18x + x2y

Combine like terms: -1x2y + x2y = 0
0 + 2x3y + -4y = -18x + x2y
2x3y + -4y = -18x + x2y

Add '-2x3y' to each side of the equation.
2x3y + -2x3y + -4y = -18x + x2y + -2x3y

Combine like terms: 2x3y + -2x3y = 0
0 + -4y = -18x + x2y + -2x3y
-4y = -18x + x2y + -2x3y

Add '4y' to each side of the equation.
-4y + 4y = -18x + x2y + -2x3y + 4y

Combine like terms: -4y + 4y = 0
0 = -18x + x2y + -2x3y + 4y

Simplifying
0 = -18x + x2y + -2x3y + 4y
