Question

3. A numbers is subtracted from seven. When the result is divided by

Answer 1

7-x=y

y/3=2

y=6

7-x=6

-x= -1

x=1

Answer 2

Answer:

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
