16+3x\times 2=3\times 6
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 3x, the least common multiple of 3x,x.
16+6x=3\times 6
Multiply 3 and 2 to get 6.
16+6x=18
Multiply 3 and 6 to get 18.
6x=18-16
Subtract 16 from both sides.
6x=2
Subtract 16 from 18 to get 2.
x=\frac{2}{6}
Divide both sides by 6.
x=\frac{1}{3}
Reduce the fraction \frac{2}{6} to lowest terms by extracting and canceling out 2.
