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