3\left(6x+7\right)-x=9
Multiply both sides of the equation by 9, the least common multiple of 3,9.
18x+21-x=9
Use the distributive property to multiply 3 by 6x+7.
18x-x=9-21
Subtract 21 from both sides.
18x-x=-12
Subtract 21 from 9 to get -12.
17x=-12
Combine 18x and -x to get 17x.
x=\frac{-12}{17}
Divide both sides by 17.
x=-\frac{12}{17}
Fraction \frac{-12}{17} can be rewritten as -\frac{12}{17} by extracting the negative sign.
