The right part in the initial equation should be 6x, not 6(6 + x).

What about the last part which is the final answer

What about the last part which is the final answer
Well, obviously, if there's a mistake in the beginning, you need to redo the whole thing.
deep crypt
Now it's good.
fervent silo
And is this correct?
deep crypt
And is this correct?
The initial equation is correct, but you didn't solve it correctly. Be more careful when opening brackets.
deep crypt
Yes.

deep crypt
Yeah, seems good.

Don't round, leave it as 97/6.
deep crypt
Correct, but I'd still prefer leaving it as an ordinary fraction: 39/5.
deep crypt
It’s just because my teacher doesn’t right it as a fraction
Well, here both 7.8 and 39/5 are exact and correct, so it's a matter of preference.
But when the fraction requires rounding to write it in decimal form, I don't do that, because the answer will not be exact.
deep crypt
That's not correct. You didn't open the brackets on the left correctly.
x(x + 10) = (x + 3)(x + 1)
x^2 + 10x = x^2 + 4x + 3
6x = 3
x = 1/2
