Question 8419
5x+8=4x+2                  <--subtract 4x from both sids
(5x+8)-4x=(4x+2)-4x
x+8=2                       <--subtract 8 from both sides
(x+8)-8=2-8
x=-6



3x-(-2x+6)=4(x-4)+x
3x+2x-6=4x-16+x
5x-6=3x-16              <--subtract 3x from both sides
(5x-6)-3x=(3x-16)-3x
2x-6=-16                   <--add 6 to both sides
(2x-6)+6=(-16)+6
2x=-10                  <--divide both sides by 2
{{{2x/2}}}={{{-10/2}}}
x=-5
