Best ResponseYou've already chosen the best response.0@shortie, because these equations are straight lines, are not a multiple of each other and have different gradients, there can only be one solution. If there were multiples they are the same line and have infinite solutions. If they had the same gradient they would be parallel lines and have no solutions.

Best ResponseYou've already chosen the best response.0Straight lines  GradientIntercept Form: y=mx+c where m is gradient, c is yintercept Standard Form: ay+bx+c=0 where a and b are constants
