-a-x=5x+3
Swap sides so that all variable terms are on the left hand side.
-a=5x+3+x
Add x to both sides.
-a=6x+3
Combine 5x and x to get 6x.
\frac{-a}{-1}=\frac{6x+3}{-1}
Divide both sides by -1.
a=\frac{6x+3}{-1}
Dividing by -1 undoes the multiplication by -1.
a=-6x-3
Divide 6x+3 by -1.
5x+3+x=-a
Add x to both sides.
6x+3=-a
Combine 5x and x to get 6x.
6x=-a-3
Subtract 3 from both sides.
\frac{6x}{6}=\frac{-a-3}{6}
Divide both sides by 6.
x=\frac{-a-3}{6}
Dividing by 6 undoes the multiplication by 6.
x=-\frac{a}{6}-\frac{1}{2}
Divide -a-3 by 6.
