A=-3xy^{2}z-2xy^{2}z
Subtract 2xy^{2}z from both sides.
A=-5xy^{2}z
Combine -3xy^{2}z and -2xy^{2}z to get -5xy^{2}z.
A+2xy^{2}z+3xy^{2}z=0
Add 3xy^{2}z to both sides.
A+5xy^{2}z=0
Combine 2xy^{2}z and 3xy^{2}z to get 5xy^{2}z.
5xy^{2}z=-A
Subtract A from both sides. Anything subtracted from zero gives its negation.
5zy^{2}x=-A
The equation is in standard form.
\frac{5zy^{2}x}{5zy^{2}}=-\frac{A}{5zy^{2}}
Divide both sides by 5y^{2}z.
x=-\frac{A}{5zy^{2}}
Dividing by 5y^{2}z undoes the multiplication by 5y^{2}z.
