6-x-5=4x

+x    +x

6-5=5x

Hi LunaMoon,

Yes that is a very good answer.

I'd just suggest that you write one last line:

x=0.2

The last line shoudl always be         pronumeral =

$$6-(x+5) = 4x$$ is the equation and we want to find $$x$$.

The minus sign in front of the parentheses means everything inside the parentheses is multiplied by -1.

For example, $$-(4)$$ equals $$-1\times 4$$, which is also just $$-4$$.

However, $$-(-2)$$ equals $$-1\times -2$$, which is $$2$$.

And $$-(3+2)$$ can be interpreted as $$-1\times 3-1\times 2$$, or $$-5$$.

Got it?

Now, $$-(x+5) = -x-5$$, so $$6-x-5 = 4x, 1-x=4x, 1 = 5x, x = \frac{1}{5}$$.

You are very welcome!

:P
