5+n-2xn=0
Subtract 2xn from both sides.
n-2xn=-5
Subtract 5 from both sides. Anything subtracted from zero gives its negation.
\left(1-2x\right)n=-5
Combine all terms containing n.
\frac{\left(1-2x\right)n}{1-2x}=-\frac{5}{1-2x}
Divide both sides by 1-2x.
n=-\frac{5}{1-2x}
Dividing by 1-2x undoes the multiplication by 1-2x.
2xn=5+n
Swap sides so that all variable terms are on the left hand side.
2nx=n+5
The equation is in standard form.
\frac{2nx}{2n}=\frac{n+5}{2n}
Divide both sides by 2n.
x=\frac{n+5}{2n}
Dividing by 2n undoes the multiplication by 2n.
x=\frac{1}{2}+\frac{5}{2n}
Divide 5+n by 2n.
