So I am doing exercises in my brothers workbook and am making slight improvement (VERY slight).



I have x = 2y + 1 and y = x +2



So if I do this....am I supposed to do it as x = 2 (x + 2) and then what? I am getting lost at this part with nearly every equation.



I have the answers but I am missing the "HOW" steps and my brain is just beyond stupid when it comes to math.



This is not homework by the way. I am just horrid at math and would like to improve. I know how I did it makes no sense but I am lost as to the correct way to do it.
