If the system has no solution, say that it is inconsistent Ox-8, y = 3; (83)

Explanation / Answer

x +5y= 2

2x+10y= 4

Multiply first eqaution by 2

2x+10y= 4

2x+10y= 4

Since both eqaution is same, equation has Infinite solution.

Now

x+5y= 2

5y= -x +2

y= -x/5 +2/5

which means option a is not correct.

Thus,

Option B is correct

x =2, y=0
