Question #c082e

Answer 1

The number is 6

Explanation:

`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`

Answer 2

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

Explanation:

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!
