Question

A number is subtracted by 10 and then divided by 3 . when 7 is added to this result is becomes 4 . what was the initial number

UpStudy AI · Accepted Answer

Let the initial number be $$ n $$.

1. The number is subtracted by 10:
   $$
   n - 10
   $$
2. Then the result is divided by 3:
   $$
   \frac{n-10}{3}
   $$
3. When 7 is added to this result, it becomes 4:
   $$
   \frac{n-10}{3} + 7 = 4
   $$

4. Solving the equation:
   $$
   \frac{n-10}{3} = 4 - 7 = -3
   $$
   Multiply both sides by 3:
   $$
   n - 10 = -9
   $$
   Add 10 to both sides:
   $$
   n = -9 + 10 = 1
   $$

The initial number is $$ 1 $$.
The initial number is 1.
