Question

If I add 10 to four times a certain number, the result is 5 less than 5 times. Find the number?

Answer 1

Answer:

Let the number be x

Form the equation:

10 be added to 4 times of x ,the result is 5 less than 4 times of x

⇒ 4x + 10 = 5x - 5

Solve x

4x + 10 = 5x - 5

5x - 4x = 10 + 5

x = 15

Hence, The number is 15.
