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!

Answer:
The ratio in which the line x-y-2=0 divides the line joining A(3,-1) and B(8,9) is in the ratio 2:3
Step-by-step explanation:
Let (x, y) be the coordinates of point of intersection.
Hence x=(a*8+1*3)(a+1) = (8a+3)/(a+1)
and
y = {a*9+1*(-1)}/(a+1)=(9a-1)/(a+1)
Since this point lies on the line x-y-2=0
Hence (8a+3)/(a+1)-(9a-1)/(a+1)-2=0
i.e. 8a+3–9a+1–2(a+1)=0
Or 8a+3–9a+1–2a-2=0
i.e.-3a+2=0
Hence a=2/3
hence the ratio in which the line x-y-2=0 divides the line joining A(3,-1) and B(8,9) in the ratio 2/3:1
i.e. 2:3

Answer:
Step-by-step explanation:
175-(8+45÷3)x7 s
start with what's inside the parenthesis
(8+45÷3) ⇒ (8+15) ⇒(23)
175-(23)x7
then do multiplication
23x7
161
175-161
14
final answer is 14
