Question 48014
Now you see, the problem  6x-(x+3)=5+2x can be rewritten as followed

 --->                    6x-1*(x+3)=5+2x

Using the rules of Distrubtion, a*(b+c)=a*b+a*c yields 6x-x-3=5+2x. 
Notice that -1*(x+3)=(-1)*x+(-1)*(-1)3
Simplfying the problem gives us                       5x-3=5+2x
minus 3 to both sides gives us                              5x=8+2x
add 2x to both sides gives us                             3x=8
                                                       x=8/3 or 2.66667
