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 differential outcomes in the above is known to be the positive influence based on accuracy that took place in discrimination learning between the functions if unique rewards are said to be paired with each specific variable.
<h3>What is differential outcomes?</h3>
The differential outcome effect (DOE) is known to be a term that connote the increase in regards to the speed of getting and also of terminal accuracy that takes place in conditional discrimination learning if two or more stimuli are said to be correlated with a specific outcome.
