-4\left(-3\right)x+3a\times 3\left(-3\right)-3=0
Multiply both sides of the equation by \left(x-3\right)\left(x+3\right).
12x+3a\times 3\left(-3\right)-3=0
Multiply -4 and -3 to get 12.
12x+9a\left(-3\right)-3=0
Multiply 3 and 3 to get 9.
12x-27a-3=0
Multiply 9 and -3 to get -27.
-27a-3=-12x
Subtract 12x from both sides. Anything subtracted from zero gives its negation.
-27a=-12x+3
Add 3 to both sides.
-27a=3-12x
The equation is in standard form.
\frac{-27a}{-27}=\frac{3-12x}{-27}
Divide both sides by -27.
a=\frac{3-12x}{-27}
Dividing by -27 undoes the multiplication by -27.
a=\frac{4x-1}{9}
Divide -12x+3 by -27.
-4\left(-3\right)x+3a\times 3\left(-3\right)-3=0
Variable x cannot be equal to any of the values -3,3 since division by zero is not defined. Multiply both sides of the equation by \left(x-3\right)\left(x+3\right).
12x+3a\times 3\left(-3\right)-3=0
Multiply -4 and -3 to get 12.
12x+9a\left(-3\right)-3=0
Multiply 3 and 3 to get 9.
12x-27a-3=0
Multiply 9 and -3 to get -27.
12x-3=27a
Add 27a to both sides. Anything plus zero gives itself.
12x=27a+3
Add 3 to both sides.
\frac{12x}{12}=\frac{27a+3}{12}
Divide both sides by 12.
x=\frac{27a+3}{12}
Dividing by 12 undoes the multiplication by 12.
x=\frac{9a+1}{4}
Divide 27a+3 by 12.
x=\frac{9a+1}{4}\text{, }x\neq -3\text{ and }x\neq 3
Variable x cannot be equal to any of the values -3,3.
-4\left(-3\right)x+3a\times 3\left(-3\right)-3=0
