2x+3y=84x+6y=7 solve by elimenation and subtitution

1.	2x+3y=84x+6y=7 solve by elimenation and subtitution
Answer» Let 2x + 3y = 8 be eq(i) and 4x + 6y = 7 be eq(ii).Now, From eq(i),2x + 3y = 82x = 8 - 3yx = (8 - 3y)/2 Putting the Value of x in eq(ii),4x + 6y = 74(8 - 3y)/2 + 6y = 72(8 - 3y) + 6y = 716 - 6y + 6y = 716 = 716 - 7 = 0\xa09 = 0That is not true.From the Calculations, We can see that the Equations has no solution.
