Hello, Aditya711!

Prove It did click on the sentence
and this is what he saw . . .

What's the answer to this equation,
and how did you solve it?

. . $2!\int^7_0(x+y)\,\frac{dy}{dx}$

I assume you wrote this . . .

Only a few things wrong with it:

There is no equation . . . so we can't solve it.

It seems to be a definite integral, so we might evaluate it.
But the integral makes no sense.
. . The $\tfrac{dy}{dx}$ is meaningless.
. . Are the "0" and "7" $x$ -limits or $y$ -limits?
. . Is that really $2!$ in front? . . . Why?
