9x-3=4\left(3+3x\right)
Use the distributive property to multiply 3 by 3x-1.
9x-3=12+12x
Use the distributive property to multiply 4 by 3+3x.
9x-3-12x=12
Subtract 12x from both sides.
-3x-3=12
Combine 9x and -12x to get -3x.
-3x=12+3
Add 3 to both sides.
-3x=15
Add 12 and 3 to get 15.
x=\frac{15}{-3}
Divide both sides by -3.
x=-5
Divide 15 by -3 to get -5.
