Sure Like I said your going to substitute y for x+3 so your going to rewrite you problem as.. x+3=4x2 The next thing you need to do is get rid of one of the x's so your going to subtract x from both sides so your new equation is.. 3=5x2 (Because its understood that x=1) Your next step is to add 2 to both sides.. 5=5x Now we want to get x by itself so we divide 5 on both sides, Giving you your final answer of 1=x
