Question

a number s is subtracted from seven. when the result is divided by three, the quotient is two. what is the number?

Answer 1

$7-S=7-S$... $\frac{7-S}{2} =3$... $7-S=6$... $-S=-1$... S=1

Answer 2

So a number s (s) is subtracted from seven (7 take away s or 7-s) when the result (7-s) is divided by 3 [(7-s)/3] the quotient is 2 (=2)

(7-s)/3=2
multiply both sdis by 3
7-s itmes 3/3=2 times 3
7-s=6
subtract 7 from both sdies
-s=-1
multily -1
s=1


the number is 1
