Anyone mind helpin me with this?

Determine which system below will produce infinitely many solutions.

-4x + 6y = 20
4x - 3y = -2

-2x + 4y = 18
4x - 8y = -36

3x - 2y = 5
-6x - 4y = -10

5x - 3y = 12
15x - 9y = 24

The 2nd one has infinite solutions

anonymous · Answer

how can you tell?

anonymous · Answer

whats the work you did to figure that out i mean ?

anonymous · Answer

nvm i figured it out, thanks love

anonymous · Answer

Use the system of equations to get an absolute truth. 
Example:
y = x+5
2y = 2x+10
If you solve this you get:
x+5 = x+5
5 = 5

If you get to a statement that is obviously false, then you have no solutions.
For example: 
y=9x+5
y=9x-2
Solving these you get to
5=-2
So there are no solutions to that.
Do you understand?
