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.

The statement is - False.
In the pre-industrial societies, the economy was far from being based on providing information and services. The economy was largely based on two things, agriculture and trade.
The agriculture was the basis and the dominant sector in the pre-industrial economy. The more agricultural products a nation had, the more it had to trade, thus becoming wealthy. This can easily be seen in the colonies that the European countries had in the pre-industrial period, where every inch of the land that was suitable for agriculture was used, and latter those products were shipped and traded in order to become wealthier.
