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!

We can rearrange 3x+y=9 to look more conventional by subtracting 3x from both sides and making it y= -3x+9.
Now we want to find a line that is parallel to this and goes through the point (0,-4). We know that -3 is the slope. With this in mind, if we want the other line to be parallel then it must have the same slope so that they never intersect. This gives us one of the numbers we need for the second line.
This means our second equation is looking like; y= -3x+b. This means we need to find b (the y-intercept) but we are also given a point it must go through and this is (0,-4). We simply plug this in into our new equation we need to solve and we get ; -4 = -3(0) + b . "since 0 is the x and -4 is the y" . From this we get that b= -4. This means the equation of a line parallel is:
y = -3x-4
Answer:
30
