Start by solving the first equation for y. so subtract 3x from both sides and divide both sides by 2. y= -3/2+1. now look at the other equation and notice they have the same slope. Because they have the same slope the two lines can never cross so there can't be a solution. heres a rough sketch|dw:1359693193574:dw|
