There are many factors, it is all a matter of preference, normally, you want to try to solve for the easiest one to get to
example
if y ou had
(x-3)^2+y=9
you would solve for y becuase it is less tricky
it is all a matter of preference
Answer:
2 three points shots and 4 two points shots
Step-by-step explanation:
Let x be the number of three points shots.
Alexander made twice as many two points shots as three points shots, so the number of two points shots is 2x.
Amount earned in three points shots
Amount earned in two points shots
Total score 
Alexander scores a total of 14 points, then

9514 1404 393
Answer:
d = |-9-4| = 13
Step-by-step explanation:
The y-values are the same for the two points, so the distance between them on that horizontal line is the difference of x-values.
d = |(-9) -(4)|
d = |-13| = 13
The distance between the points is 13 units.
