G Guest Guest Sep 7, 2006 #3 Hi Austinj This is the way I would approach this question: \(\displaystyle \large\\4x-7y=10\\ -7y=-4x+10\\ -y=-\frac{4x}{7}+\frac{10}{7}\) Therefore we times it all by -1. That way y is positive!! You should end up with \(\displaystyle \large\\y=\frac{4x}{7}-\frac{10}{7}\)
