3x-20=12x-6x+43
Subtract 11 from -9 to get -20.
3x-20=6x+43
Combine 12x and -6x to get 6x.
3x-20-6x=43
Subtract 6x from both sides.
-3x-20=43
Combine 3x and -6x to get -3x.
-3x=43+20
Add 20 to both sides.
-3x=63
Add 43 and 20 to get 63.
x=\frac{63}{-3}
Divide both sides by -3.
x=-21
Divide 63 by -3 to get -21.
