Answer 1

Answer:

$\sf{\pink{Let \: the \: number \: be \: x}}$

$\green{According \: to \: the \: Question,}$

$3x + 15 = 5x + 3$

$5x - 3x = 15 - 3$

$2x = 12$

$x = \frac{12}{2}$

$x = 6$

$\sf{\pink{Therefore, \: The \: number \: is \: 6.}}$

Answer 2

Answer:

The number is 6.

Step-by-step explanation:

Let the number be x.

Here we have,

15 added to thrice a number. This means,

LHS will be,

3x + 15.

Now we have,

3 added to five times the number. This means,

5x + 3.

Now lets equate them.

This gives,

3x + 15 = 5x + 3

15 - 3 = 5x - 3x

12 = 2x

x = 6.

Therefore the number is 6.
