To determine the answer, the first step is to apply distributive property.
Why it became positive? Notice that - (-6x), there is a negative sign inside and outside the parentheses. Since both of them are negative, we can say that when two negative numbers are multiplied together, it will became positive.

Hi student, let me help you out!

First, let's recall what [tex]\mathtt{a-(-b)}[/tex] is equal to.
[tex]\mathtt{a-(-b)=a+b}[/tex]. Please remember that.
Now, let's use this little rule to simplify our expression, which is [tex]\mathtt{x-(-6x)}[/tex].
We already know that [tex]\mathtt{x-(6x)=x+6x}[/tex].
Now it's just a matter of combining like terms: [tex]\mathtt{x+6x=7x}[/tex]
Thus, the expression [tex]\mathtt{x-(-6x)}[/tex] equals [tex]\bigstar\underline{\boxed{\mathtt{7x}}}[/tex].
Hope this helped you out, ask in comments if any queries arise.
