2m-2n=x+7
Use the distributive property to multiply 2 by m-n.
2m=x+7+2n
Add 2n to both sides.
2m=x+2n+7
The equation is in standard form.
\frac{2m}{2}=\frac{x+2n+7}{2}
Divide both sides by 2.
m=\frac{x+2n+7}{2}
Dividing by 2 undoes the multiplication by 2.
m=\frac{x}{2}+n+\frac{7}{2}
Divide x+7+2n by 2.
2m-2n=x+7
Use the distributive property to multiply 2 by m-n.
-2n=x+7-2m
Subtract 2m from both sides.
-2n=x-2m+7
The equation is in standard form.
\frac{-2n}{-2}=\frac{x-2m+7}{-2}
Divide both sides by -2.
n=\frac{x-2m+7}{-2}
Dividing by -2 undoes the multiplication by -2.
n=-\frac{x}{2}+m-\frac{7}{2}
Divide x+7-2m by -2.
