nine more= +9
quotient= division
equals =
an unknown number = x
Let start the problem backward : x/ 4 + 9 = 3 That is your solution.
Note: if the problem ask to find the "number" x .
Multiply each term by 4. x +36 =12. , subtract 12-36=x and you get x= -24 and this is how you check your answer. -24/4. +9 =3
-6 +9 =3
3=3
