Best ResponseYou've already chosen the best response.0are those supposed to be two equations describing the same variable?! if so, no value of a would satisfy both equations

Best ResponseYou've already chosen the best response.0my bad, the equation is 2x+ay=4 and ax+8y=8

Best ResponseYou've already chosen the best response.0first, combine equations to make it in the form ax^2 + bx + c = 0 (quadratic form). where 'x' is 'a' in this case

Best ResponseYou've already chosen the best response.0another approach to have infinite solutions equation 1 would be equal to equation 2 to make them equal multiply the first equation by 4 8 = 8 so 4x + 2ay = 8 and ax + 8y = 8 therefore when a = 4

Best ResponseYou've already chosen the best response.0I did not post because not sure. The no solution situation is when the solution for equation one when substituted in equation 2 will not make the equation true.
