Question

determine the value of'k' do that the following equations have no solutions.
2X+3Y=7,6X-3Y=24​

Answer 1

Answer:

x = 31/8 or 3.875

y= -5

Step-by-step explanation:

if 2x+3y=7

6x-3y=24

therefore adding both equations together we get

2x+3y+6x-3y=7+24

8x=31

x=31/8

therefore 2x+3y=7

2(31/8)+3y=7

81/4+3y=7

(81+12y)/4=7

12y=28-81

y=-5
