185x+77z=d-10y
Subtract 10y from both sides.
185x=d-10y-77z
Subtract 77z from both sides.
185x=d-77z-10y
The equation is in standard form.
\frac{185x}{185}=\frac{d-77z-10y}{185}
Divide both sides by 185.
x=\frac{d-77z-10y}{185}
Dividing by 185 undoes the multiplication by 185.
x=\frac{d}{185}-\frac{2y}{37}-\frac{77z}{185}
Divide d-10y-77z by 185.
d=185x+10y+77z
Swap sides so that all variable terms are on the left hand side.
