3-2x-6=4x+3\left(x-4\right)+3
Use the distributive property to multiply -2 by x+3.
-3-2x=4x+3\left(x-4\right)+3
Subtract 6 from 3 to get -3.
-3-2x=4x+3x-12+3
Use the distributive property to multiply 3 by x-4.
-3-2x=7x-12+3
Combine 4x and 3x to get 7x.
-3-2x=7x-9
Add -12 and 3 to get -9.
-3-2x-7x=-9
Subtract 7x from both sides.
-3-9x=-9
Combine -2x and -7x to get -9x.
-9x=-9+3
Add 3 to both sides.
-9x=-6
Add -9 and 3 to get -6.
x=\frac{-6}{-9}
Divide both sides by -9.
x=\frac{2}{3}
Reduce the fraction \frac{-6}{-9} to lowest terms by extracting and canceling out -3.
