Think of a number, multiply it by 5, subtract 15 from the result if your answer is 25, what is the number?

1 answer

Let's call the number we're trying to find "x."

According to the problem, we need to follow these steps:

1. Multiply the number by 5: 5x
2. Subtract 15 from the result: 5x - 15

Now we know that if our answer is 25, then:

5x - 15 = 25

To solve for x, we can add 15 to both sides of the equation:

5x - 15 + 15 = 25 + 15

Simplifying, we get:

5x = 40

Finally, we can solve for x by dividing both sides by 5:

x = 8

Therefore, if we start with the number 8, then when we multiply by 5, we get 40. When we subtract 15 from 40, we get 25.
