6d=9-5x
Subtract 5x from both sides.
\frac{6d}{6}=\frac{9-5x}{6}
Divide both sides by 6.
d=\frac{9-5x}{6}
Dividing by 6 undoes the multiplication by 6.
d=-\frac{5x}{6}+\frac{3}{2}
Divide 9-5x by 6.
5x=9-6d
Subtract 6d from both sides.
\frac{5x}{5}=\frac{9-6d}{5}
Divide both sides by 5.
x=\frac{9-6d}{5}
Dividing by 5 undoes the multiplication by 5.
