Best ResponseYou've already chosen the best response.3No. 2x  y = 7 > by 2 > 4x 2y = 14 Add that to the second equation

Best ResponseYou've already chosen the best response.3No. 0 + 0 = 0 4x 2y = 14 is the same line as 4x +2y = 14. If you multiply 4x +2y = 14 by 1, you will get the first equation. So, there is only one line here. Or, you can say that they coincide in every point.

Best ResponseYou've already chosen the best response.3Your equations intersect in every point. Look on the attached chart and read how many solutions there are. That is the answer to this question.
