Answer:
0, 1, 2
Step-by-step explanation:
The solution to a system of equations given graphically is at the intersection of the individual graphs.
Graph (1)
There is no intersection between the 2 graphs so no solution
Graph (2)
There is one point of intersection between the 2 graphs so 1 solution
Graph (3)
There are two points of intersection between the 2 graphs so 2 solutions
-6
Multiply both sides by 2.
Multiply 6 and 2 to get 12.
Subtract 3 from both sides.
Subtract 3 from 12 to get 9.
