3\left(x-2\right)\times \frac{1}{3}+3\times 4=18\left(x-2\right)
Variable x cannot be equal to 2 since division by zero is not defined. Multiply both sides of the equation by 3\left(x-2\right), the least common multiple of 3,x-2.
\left(3x-6\right)\times \frac{1}{3}+3\times 4=18\left(x-2\right)
Use the distributive property to multiply 3 by x-2.
x-2+3\times 4=18\left(x-2\right)
Use the distributive property to multiply 3x-6 by \frac{1}{3}.
x-2+12=18\left(x-2\right)
Multiply 3 and 4 to get 12.
x+10=18\left(x-2\right)
Add -2 and 12 to get 10.
x+10=18x-36
Use the distributive property to multiply 18 by x-2.
x+10-18x=-36
Subtract 18x from both sides.
-17x+10=-36
Combine x and -18x to get -17x.
-17x=-36-10
Subtract 10 from both sides.
-17x=-46
Subtract 10 from -36 to get -46.
x=\frac{-46}{-17}
Divide both sides by -17.
x=\frac{46}{17}
Fraction \frac{-46}{-17} can be simplified to \frac{46}{17} by removing the negative sign from both the numerator and the denominator.
