    @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.

    Straight lines ---- Gradient-Intercept Form: y=mx+c where m is gradient, c is y-intercept Standard Form: ay+bx+c=0 where a and b are constants

    Thanks Zed, just hate when people type an answer in a study group and not explain themselves. People should come here to learn, not have someone do their homework for them :)
