Looking at this, I think the easiest (personally) way to solve it would be using the Substitution method.
Meaning we have to rearrange ONE equation, to make ONE variable ( x or y) the subject.
(1) 2.5x + y = -2
(2) 3x +2y = 0
The first equation is the easiest to rearrange. Make Y the subject for (1).
Thus,
y = -2.5x - 2
Substitute this into equation (2).
∴ 3x + 2(-2.5x - 2) = 0
Expand and simplify:
3x - 5x - 4 = 0
∴ -2x - 4 = 0
Making x the subject:
-2x = 4
x = -2
From here, we need to substitute x=-2 into equation (1) or (2) to solve for the y-value. I would say the easiest way, would be to rearrange one, to make y the subject, which was what we did earlier.
Thus,
y = -2.5x - 2
y = ((-2.5(-2) -2)
y = 3
(X,Y) x = -2, y = 3
Answer: (-2,3)
I hope you followed through.
Answer:
Can you justify a correlation between number of cats falling and months of the year?

The lower temperature months tend to have lower cats falling and the higher temperature months tend to have a higher number of cats falling.
Is this comprehensive writing?
I must say if it is, it's great writing!
If not, is this your experience?
{And if it is, am so sorry. I can't say I understand what you're passing through but know that you and your siblings plus your mom are worth it. All the male parent figures that were supposed to be there and fufill their duties and didn't just know that what awaits them is God's payment. Trusting in God's Way will never let us down. Though life might look bleary and you said so that you don't know the future but that's the beauty of life only God knows. Therefore, pray without ceasing and trust in God and remember there are a lot of things to be thankful for your life, your mom, your siblings, your education, your bf.
(God is always saying something)
Much love to you. I pray everything gets better for you. The best is always yet to come.}
All the best! :)
