There are 2 ways to do this with elimination method. You can either multiply the first equation by 6 or the second equation by 2. I think multiplying by 2 is easier therefore that's the way I'm going to show you.
x-2y=3001️⃣
6x-y-95=0 -simplify> 6x-y=952️⃣
multiply both sides of second equation by 2 to make 2y and eliminate
2️⃣*2
12x-2y=1903️⃣
Now we can eliminate!
3️⃣-1️⃣
12x-2y-(x-2y)=190-300
11x=-110
x=-10
Now substitute this back into either of the equations.
-10-2y=300
2y=-10-300
y=-155
So we get answers
x=-10
y=-155
Now check our work:
-10- 2*-155=-10+310=300 Correct!
6*-10- -155-95=155-95-60=60-60=0 Correct!
I really hope this helped you and if you have any more question about a step in how I got the answer, you can always ask in the comments and I will come answer whenever I see it!
ANSWER
Infinitely many solutions.
EXPLANATION
The given system t;
8x + 9y = –5
–8x – 9y = 5
We use the elimination method:
Let us add the two equations to obtain:
-8x+8x+9y-9y=-5+5
This simplifies to:
0=0
This implies that, the system has infinitely many solutions because the two lines coincide.

sin∠D =
The lower bound is the smallest value that rounds up to the given value.
Given value = 4m
The lower bound would be 3.5m
Any number less than .5 rounds down, any number greater to or equal to 0.5 rounds up, so if you have 3.5 or higher it rounds to 4
