Answer:
(x, y) = (61/23, 36/23)
Step-by-step explanation:
We assume you intend the equations to be ...
Then in general form, they are ...
5x -4y -7 = 0
2x +3y -10 = 0
The solution using the "cross multiplication method" is ...
1/(15 +8) = x/(40+21) = y/(-14 +50)
(x, y) = (61/23, 36/23)

<em>Comment on "cross multiplication method"</em>
When the coefficients from the general form equations are written as a 2×4 array with the first and last columns the same ...
the solution is 1/d1 = x/d2 = y/d3, where d1, d2, d3 are the determinants of successive pairs of columns.
- d1 = (5)(3) -(2)(-4)
- d2 = (-4)(-10) -(3)(-7)
- d3 = (-7)(2) -(-10)(5)
Answer:
Explanation:
Here, we want to get if the given variable is qualitative or quantitative
While qualitative describes the presence of a quality, quantitative speaks about count or number
Thus, what we have here is that we are talking about likeness and not about the count of basketball players. Thus, in this case, a certain basketball player is liked to be called a favorite because of some of the qualities he/she possesses
Thus, we can conclude that the variable is qualitative
