Let x be the unknown number. Then the quotient of a number and 6 is:
[tex]\frac{x}{6}[/tex]To this be substract 3:
[tex]\frac{x}{6}-3[/tex]Now, this is 1, then:
[tex]\frac{x}{6}-3=1[/tex]Now we solve the equation,
[tex]\begin{gathered} \frac{x}{6}-3=1 \\ \frac{x}{6}=1+3 \\ \frac{x}{6}=4 \\ x=4\cdot6 \\ x=24 \end{gathered}[/tex]Therefore, x=24.
