\left(5-7\right)n
Subtract the numbers
-2n
-2n+6
-2n+6=0
Move the constant to the right-hand side and change its sign
-2n=0-6
Removing 0 doesn't change the value,so remove it from the expression
-2n=-6
Change the signs on both sides of the equation
2n=6
Divide both sides
\frac{2n}{2}=\frac{6}{2}
Divide the numbers
n=\frac{6}{2}
