Well if 2x+3 is less than or equal to one, then take the three over to the other side. This means that 2x is less than or equal to -2. Divide through by two so that x is less than or equal to -1. The rest is a little trickier to visualise without a diagram I'm afraid. However if you draw both on a graph and mark on where the two lines meet you'll have your answer.
