Ok, you're going to have x + 2y = 3 Well you want to get y alone to start. So you are going to make x a negative x and subtract that from 3. So you have 2y = 3 + - x Well, for the next step, you want to get y alone, so you are going o get rid of the two. But how? Well, whacha want to do is divide y = 3 + - x --------- 2 2Divide each side by 2. so you have 3/2 and x/2. Can you take it from there? Divide hose and put it mx+b form. If you need anymore help, please send me a message and I will be happy to explain further.
