Question

Pls help me???????????

Answer 1

the number's 5

Explanation:

because 5x+15 will never equal 5x-3 no matter what x is

Answer 2

Hi! I hope you're enjoying your day!

The missing number is 5.

Why 5? You'll see...

So the equation is

5x+15=5x-3

Is this right? We need to check.

Let's plug in 1.

5(1)+15=5(1)-3

5+15=5-3

20=-2

See? We ended up with a false statement.

There's no way 20 is going to equal -2.

Let's try 2:

5(2)+15=5(2)-3

10+15=10-3

25=7

Once again, we have a false statement.

You could try any number. You could try 5, 12, 150, 2710...

No matter which number you choose, you will always have a false statement.

Hence, the missing number is

`\boxed{\boxed{\bold{5}}}`

But hey!! Why 5?!

Because no matter which number you pick, you will always have a false statement.

There's no number that can satisfy the following equation:

5x+15=5x-3

Basically, you take a number x, multiply it times 5, add 15, and that's supposed to equal the same number times 5 and minus 3?!

Hope everything is clear.

If you have any questions, please ask.
