A linear equation represents a straight line.Thus, the solution of the system of linear equation depends on whether the lines intersect, not intersect or same line.
We have below cases:-
- The lines are non parallel and intersect at exactly one point. In this case we have one solution.
- The lines are parallel and hence never intersect. There is no solution in this case.
- The two lines represents the same line. Hence, infinitely many solutions.
We never got exactly two solutions because two lines can intersect at a single point.

Step-by-step explanation:
Answer:
540 SUV's
Step-by-step explanation:
Sales percentage of non SUV's = 100 - 60 = 40%
Let total cars be x
40% of x = 360
Number of SUV's = Total cars - number of non SUV's
= 900 - 360
= 540
B) 2x+1 < 7 and -2x +1 < 9
C) -4 < x < 3
D) -4 <[equal to] x <[equal to] 3
