Question 878487: Determine if the system has 1 solution, no solutions, or zero solutions:
5x-15y=35
15y-10x=-20

5x-15y=35
15y-10x=-20
is the same as
5x-15y=35
-10x+15y=-20
Add the two equations to get
5x-15y=35
-10x+15y=-20
-------------
-5x+0y = 15
So -5x = 15
This means that we can solve for x to get a specific number. We then use that solution for x to solve for y.
Overall, this system has 1 solution.
