Best ResponseYou've already chosen the best response.1solving a system of equations and "all real numbers" are unrelated. However, you can solve these problems by graphing, elimination, substitution, or using matrices.

Best ResponseYou've already chosen the best response.1we can use elimination method 4xy=8 (first) 8x+2y=5 (second) so let's multiply the entire first equation by 2 2(4xy=8)

Best ResponseYou've already chosen the best response.1yes and we're left with 0 = 11 is that a true statement or a false statement?

Best ResponseYou've already chosen the best response.1yup because 0 is NEVER EQUAL to 11 when the x and y values cancel out, we have an inconsistent system. An inconsistent system means that there is no solution There is no x and no y value that will satisfy these equations. So we're done. :)
