\left(x-3\right)\times 3-\left(2x+8\right)=\left(2x-6\right)\times 3
Variable x cannot be equal to any of the values -4,3 since division by zero is not defined. Multiply both sides of the equation by 2\left(x-3\right)\left(x+4\right), the least common multiple of 2x+8,x-3,x+4.
3x-9-\left(2x+8\right)=\left(2x-6\right)\times 3
Use the distributive property to multiply x-3 by 3.
3x-9-2x-8=\left(2x-6\right)\times 3
To find the opposite of 2x+8, find the opposite of each term.
x-9-8=\left(2x-6\right)\times 3
Combine 3x and -2x to get x.
x-17=\left(2x-6\right)\times 3
Subtract 8 from -9 to get -17.
x-17=6x-18
Use the distributive property to multiply 2x-6 by 3.
x-17-6x=-18
Subtract 6x from both sides.
-5x-17=-18
Combine x and -6x to get -5x.
-5x=-18+17
Add 17 to both sides.
-5x=-1
Add -18 and 17 to get -1.
x=\frac{-1}{-5}
Divide both sides by -5.
x=\frac{1}{5}
Fraction \frac{-1}{-5} can be simplified to \frac{1}{5} by removing the negative sign from both the numerator and the denominator.
