You can put this solution on YOUR website!
3 - 3x = -3x - x
...
Isolate x variables to one side
3+-+cross%283x%29+%2B+cross%283x%29+=+-3x+-+x+%2B+highlight%283x%29
...
Combine like terms
3 = -3x - x + 3x
...
3 = -x
...
Divide both sides by -1
3%2Fhighlight%28-1%29+=+cross%28-1%29x%2Fcross%28-1%29+
...
highlight_green%28x+=+-3%29
