SOLUTION: use the confficient to define w/c system hand one sol'vn infinitely many or no solution 1) 2x+y=10 2x-3y=5 2) 4y-6x=1 2y-3x=4 3) x+y=2 2x+2y=4 4) 4x+5y

Question 622320: use the confficient to define w/c system hand one sol'vn infinitely many or no solution

1) 2x+y=10
2x-3y=5

2) 4y-6x=1
2y-3x=4
3) x+y=2
2x+2y=4
4) 4x+5y=12
2x-y=6
5) y=3x-5
-6x+2y=-10

Hi,

3) x+ y=2

  2x+2y=4 

5) y=3x-5

 -3x +y =-5

 -6x+2y=-10     | 3) and 5) The systems are identical Lines, Infinite amount of Solutions



2) 4y-6x=1

   2y-3x=4    | multiplying 2nd thru by -2,   0 ≠ -7  NO solution



1) 2x+y=10

   2x-3y=5   (4.375,1.25)     

4) 4x+5y=12

   2x-y=6     (3,0)
