For this case we have, let "x" be the variable that represents the incognito number, then, if that number is subtracted 2 we have:
[tex]x-2[/tex]
On the other hand, if we divide that expression by 5, we have 3.5, so:
[tex]\frac {x-2} {5} = 3.5[/tex]
Thus, the equation is given by: [tex]\frac {x-2} {5} = 3.5[/tex]
Answer:
[tex]\frac {x-2} {5} = 3.5[/tex]
