Question 664822
1) add the -x and 3x which will equal to 2x because 3x-(1)x=2x: {{{2x+2=3-2}}}

2) then add 3-2 which equals 1:  {{{2x+2=1}}}

3) now move the +2 to the other side by subtracting it on both sides 2x+2-2=1-2: {{{2x=1-2}}}

4) 1-2=-1:  {{{2x=-1}}}

5) to get the x by itself divide each side by 2: {{{2x/2=-1/2}}} 

6) the answer is {{{x=-1/2}}}
