10x=25+y
Add y to both sides.
10x=y+25
The equation is in standard form.
\frac{10x}{10}=\frac{y+25}{10}
Divide both sides by 10.
x=\frac{y+25}{10}
Dividing by 10 undoes the multiplication by 10.
x=\frac{y}{10}+\frac{5}{2}
Divide 25+y by 10.
-y=25-10x
Subtract 10x from both sides.
\frac{-y}{-1}=\frac{25-10x}{-1}
Divide both sides by -1.
y=\frac{25-10x}{-1}
Dividing by -1 undoes the multiplication by -1.
y=10x-25
Divide 25-10x by -1.
