Question

Sonia thinks of a number. If she adds 13 to it and divide the sum by 5, she will get 10.

Answer 1

Step-by-step explanation:

Let,

• The number = x

If she adds 13 to the unknown number

• x + 13

Now she divided the unknown number with 5

• $\frac{(x + 13)}{5}$

Then she got 10 as resultant

• $\frac{(x + 13)}{5} = 10$
• $(x + 13) = 10 \times 5 \\ \\ (x + 13) = 50 \\ \\ x = 50 - 13 \\ \\ x = 37$
