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!
