Question

Karla writes this sentence: Four times a number is equal to the number increased by 15. Enter the equation that represents Karla's sentence into the box. Use y for the variable.

Answer 1

4y = y+15. This is the equation

Answer 2

Solution :-

Let the number be 'y'

Then, Four times y = 4*y = 4y

Four times a number 'y' equals to the number increased by 15 -

⇒ 4y = y + 15

The required equation is 4y = y + 15

Now, solving this equation and finding the value of y

⇒ 4y = y + 15

⇒ 4y - y = 15

⇒ 3y = 15

⇒ y = 15/3

⇒ y = 5

So, the value of y is 5
