4x+2(x+1)=9 4x+22(x+1)=92 4x(x+1)=7 4x=7 4x/4=7/4 x=1.75 Sorry I meant to put positive 1.75 not negative. But I still have a feeling that my answer is incorrect.

4x+2(x+1)=9 4x+22(x+1)=92 itself is incorrect. why did u subtract 2 ? and its not done properly

okay. so what is the first step to do? I have not had math in about a year so I need some refreshing. My teacher gave us practice problems for the first day, so she didn't teach or go over anything, so I am very lost.

4x+2(x+1)=9 1st step is to simplify 2(x+1) by distributing dw:1389463858607:dw

4x+2(x+1)=9 4x+2x+2=9 now subtract 2 from both sides.
