-x=5-10y
Subtract 10y from both sides.
\frac{-x}{-1}=\frac{5-10y}{-1}
Divide both sides by -1.
x=\frac{5-10y}{-1}
Dividing by -1 undoes the multiplication by -1.
x=10y-5
Divide 5-10y by -1.
10y=5+x
Add x to both sides.
10y=x+5
The equation is in standard form.
\frac{10y}{10}=\frac{x+5}{10}
Divide both sides by 10.
y=\frac{x+5}{10}
Dividing by 10 undoes the multiplication by 10.
y=\frac{x}{10}+\frac{1}{2}
Divide 5+x by 10.
