The number is 6

$16+x/3=3x$

$3x-x/3=16$

$x(3-1/3)=16$

$x(9/3-1/3)=16$

$x(8/3)=16$

$x=(16xx3)/(8)=48/8=6$

The number is $color(red)(6)$

Let $x = "the number"$ .

Then $16+ 1/3x = 3x$

Multiply both sides by $3$ .

$48+x=9x$

Subtract $x$ from each side.

$48 = 8x$

Divide each side by $8$ .

$6=x$

The number is $6$ .

Check:

$16+ 1/3x = 3x$

$16 + 1/3×6 = 3×6$

$16+2 = 18$

$18=18$

It works!
