3\left(3x+1\right)-18=4x
Multiply both sides of the equation by 6, the least common multiple of 2,3.
9x+3-18=4x
Use the distributive property to multiply 3 by 3x+1.
9x-15=4x
Subtract 18 from 3 to get -15.
9x-15-4x=0
Subtract 4x from both sides.
5x-15=0
Combine 9x and -4x to get 5x.
5x=15
Add 15 to both sides. Anything plus zero gives itself.
x=\frac{15}{5}
Divide both sides by 5.
x=3
Divide 15 by 5 to get 3.
