ANSWER
The number is 18.
EXPLANATION
Let the number be x.
When this number is divided by 3, we obtain the quotient,
[tex] \frac{x}{3} [/tex]
When 5 is subtracted from this quotient, we get,
[tex] \frac{x}{3} - 5[/tex]
If the result is 1, then we have;
[tex] \frac{x}{3} - 5 = 1[/tex]
We group similar terms to get,
[tex] \frac{x}{3} = 1 + 5[/tex]
This gives us,
[tex] \frac{x}{3} = 6[/tex]
Multiply both sides by 3.
[tex]x = 6 \times 3[/tex]
[tex]x = 18[/tex]
Therefore the number is 18.
