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)

The capital on 31 January 2020 was approx $ 50000 as the owner has not make any drawing this year. Hence option B is correct
<h3>
What is capital?</h3>
Capital is defined as the total amount of financial resources needed to manufacture goods or services. These cash may be employed to start up operations, cover ongoing costs, or develop and extend the company.
As given profit made this year = $ 10000
So the capital on 31 January 2020 = approx $ 50000
Thus, the capital on 31 January 2020 was approx $ 50000 as the owner has not make any drawing this year. Hence option B is correct
