Hey!


The first step to solving the rest of this problem would be to distribute the parenthesis in -( 5x - 10 ).

<em>Original Equation :</em>
-( 5x - 10 )

<em>New Equation {Changed by Distributing the Parenthesis} :</em>
- ( 5x ) - ( -10 )

Now we'll simplify the equation.

<em>Old Equation :</em>
- ( 5x ) - ( -10 )

<em>New Equation {Simplified} :</em>
-5x + 10

Okay, now that that part of the equation has been changed, we can add the simplified part to our entire equation.

<em>New Equation :</em>
5x - 9 - 5x + 10

Next we need to group like terms.

<em>Old Equation :</em>
5x - 9 - 5x + 10

<em>New Equation {Changed by Grouping Like Terms} :</em>
5x - 5x - 9 + 10

And now we add the similar elements.

<em>Old Equation :</em>
5x - 5x - 9 + 10

<em>New Equation {Changed by Grouping Like Terms} :</em>
-9 + 10

And finally we simply add the numbers.

<em>Old Equation :</em>
-9 + 10

<em>Solution {Old Equation Solved} :</em>
1

<em>So, this means that 5x - 9 - ( 5x - 10 ) is</em>  1.

Hope this helps!
