ax+3x-2xa-6a=0
Use the distributive property to multiply x by 3-2a.
-ax+3x-6a=0
Combine ax and -2xa to get -ax.
-ax-6a=-3x
Subtract 3x from both sides. Anything subtracted from zero gives its negation.
\left(-x-6\right)a=-3x
Combine all terms containing a.
\frac{\left(-x-6\right)a}{-x-6}=-\frac{3x}{-x-6}
Divide both sides by -x-6.
a=-\frac{3x}{-x-6}
Dividing by -x-6 undoes the multiplication by -x-6.
a=\frac{3x}{x+6}
Divide -3x by -x-6.
ax+3x-2xa-6a=0
Use the distributive property to multiply x by 3-2a.
-ax+3x-6a=0
Combine ax and -2xa to get -ax.
-ax+3x=6a
Add 6a to both sides. Anything plus zero gives itself.
\left(-a+3\right)x=6a
Combine all terms containing x.
\left(3-a\right)x=6a
The equation is in standard form.
\frac{\left(3-a\right)x}{3-a}=\frac{6a}{3-a}
Divide both sides by 3-a.
x=\frac{6a}{3-a}
Dividing by 3-a undoes the multiplication by 3-a.
