Best ResponseYou've already chosen the best response.0look, what do you multiply x by to get the 2x in the second.... 2 is y in the second also 2 times the first...here it is not

Best ResponseYou've already chosen the best response.0no solutions mean they are parallel, same slopes, if you want to put them both in y=mx+ b and see if they have same m

Best ResponseYou've already chosen the best response.0Solve for x and y Add both equations: A) x + y = 6 B) 2x  y = 3 3x =9 Therefore x =3 Substitute x=3 into A) x + y = 6 to get the y value

Best ResponseYou've already chosen the best response.0\[x+y=6\\2xy=3\\ ratios\ of\ their\ coefficients\ are\ \not\ equal\\i.e.\ \frac{ 1 }{ 2 }\neq \frac{ 1 }{ 1 }\\so\ system\ has\ unique\ solution\\ clearly\ \it\ has\ one\ solution\ (option,b)\]
